Chapter Four
Fort Croghan

May 31, 1842, Captain John H. K. Burgwin, under orders from the War Department established a military cantonment, for the protection of the Pottawattamie Indians against threatened attack by the Sioux, the garrison consisting of one company of dragoons.

July 1, 1842, the Captain reported to the Adjutant General of the Army, from "Camp Fenwick, on the Missouri river near Council Bluffs", that he had established encampment as above set forth.

October 7, 1842, in connection with report as to condition of his command and post. Captain Burgwin suggested the substitution of the name '"Fort Croghan"" for the station in lieu of "Camp Fenwick."

November 8, 1842, Brigadier General R. Jones, Adjutant General, approved the suggestion of Captain Burgwin, and thereafter the cantonment was known as "Fort Croghan", being so indicated on a map published by the War Department in 1843' in connection with the report of the explorations made by J. N. Nicollet and Lieutenant John C. Fremont, 1838-9.

When it became definitely determined, against earnest protest by Captain Burgwin, that the post should be maintained during the ensuing winter, due preparation was made by the erection of log quarters for the officers and men and suitable protection for the animals; the tents theretofore used were stored, and the cantonment assumed a more permanent appearance.

April 17, 1843, from "Fort Croghan, I. T." Captain Burgwin reported the greatest rise in the Missouri river known within seven- teen years; that his camp was threatened by the flood and he had prepared for removal "to the Bluffs, which are about six miles from me".

August 15, 1843, still using the "Fort Croghan" heading, the Captain reported the original camp yet surrounded by water ; that it would probably not be fit for future use ; that troops were no longer needed in the locality, and requested relief from further duty there. His request was granted and the command returned to Fort Leavenworth, from which place the Captain submitted report, dated October 13, 1843, saying that his command had just arrived and that Fort Croghan was abandoned on the 6th of that month.

The foregoing brief sketch of "Fort Croghan" is compiled from unpublished orders, reports and letters in the files of the office of the Adjutant General, War Department, Washington. The use of the date line ''Fort Croghan, I. T." by Captain Burgwin clearly fixes the site of the cantonment on the east (left) bank of the Missouri river. In his "American Fur Trade of the Far West" (Vol. 3, page 950), General Hiram Martin Chittenden says that: "Fort Croghan stood a little above the Union Pacific bridge in Omaha;" but he is mistaken, as Captain Burgwin's report dated April 17, 1843, clearly demonstrates.

The fact that Captain Burgwin continued to use the headline ' ' Fort Croghan" after the removal of the command to the highlands, indicates that the name applied to the territory under his jurisdiction rather than to the cantonment itself or to its precise site.

The precise plot of ground upon which the original location of "Camp Fenwick" and "Fort Croghan" was made, or whether the log structures of 1843 were erected upon that identical spot, is not known and may never be positively determined ; nor is there attainable evidence to show conclusively to what place Captain Burgwin referred when he reported:
"I commenced yesterday morning moving the public property to the Bluffs which are about six miles from me" —
the point to which the troops removed and took position that was maintained during the remainder of their stay in the vicinity. No records exist containing specific descriptions of these sites or either of them.

Probably the most circumstantial reference to and description of the two points occupied by Captain Burgwin as "Fort Croghan" heretofore published, is contained in an article that appeared in the Annals of Iowa (3d Series, Volume 3, page 471), which is here reproduced in full, viz. :
"Fort Croghan. — In April, 1842, while the Pottawattamie Indians were located in what is now the eastern part of Potta- wattamie County, it was thought necessary to send up the Missouri river a detachment of troops for their protection. Captain John II. K. Burj^'win therefore arrived on a steamer from Fort Leavenwortii, with a company of United States troops, and established a post on the edge of the timber at Section 10, near the present southwest corner of the city of Council Bluffs. Tliis he first named 'Camp Fenwick', but afterwards changed it to 'Fort Croghan'. There has been some dispute about the location, but 'there is certain evidence', says Hon. D. C. Bloomer, 'that it stood as mentioned'. The troops staid there during the remainder of 1842, and until the spring of 1843, when a great flood covered the Missouri Bottoms compelling the command to remove to a temporary location on the western side of Little Mosquito Creek, on the high grounds later occupied by Mr. J. P. Casady for farming purposes. Here they remained until the water, which covered the valley, subsided, when they returned to the fort. In September, following, the presence of the troops being no longer necessary for the protection of the Indians, the company, still under the command of Capt. Burgwin, returned to Ft. Leavenworth, and 'Fort Croghan' was abandoned, never again to be occupied. For the above information we are indebted to Hon. D. C. Bloomer, of Council Bluffs."
As stated elsewhere in this work the writer resided at Council Bluffs from 1853 to 1874, and was very familiar with the surrounding country, having gunned for ducks, prairie chickens, turkeys and other game, pretty much all "round about there", and, upon reading the foregoing article, a few months ago, he was surprised by some of the statements therein contained ; doubted that the original encampment of Captain Burgwin was located upon "Section 10" and knew that J. P. Casady 's farm was not near the Little Mosquito creek, but on Pony creek, some three miles south and one mile east of the mouth of the Little Mosquito. So, contemplating the writing of this paper, he began investigating.

Mr. Edgar R. Harlan, Curator of the Historical Department of Iowa, at Des Moines, under the direction of whom Annals of Iowa is now published, has furnished copies of letters sent to Hon. Charles Aldrich, founder of the Historical Department of Iowa, by Mr. Bloomer, including that "certain evidence" referred to in the article quoted above. There are two letters from Mr. Bloomer dated, respectively, November 24 and 25, 1896, the latter being in correction of a clerical error in and elaborative of the former. Both are here quoted to the end that the entire matter may be fairly placed before the reader.

"Council Bluffs, Iowa, Nov. 24, 1896.
"Hon. Charles Aldrich,
Des Moines, Iowa.
"Dear Sir:

"I return the correspondence relative to Fort Croghan and its occupancy by U. S. troops in 1842-3.

"The question as to the actual location of Camp Fenwick, changed to Fort Croghan, has elicited a good deal of controversy among the people in this section. I have spent a good deal of time and made some journeys in order to settle it in my own mind. Some claim that it was on the west side of the river, up in the \'icinity of Old Fort Atkinson, later known as Fort Calhoun. Others claim that it was on the east side of the river, on the wide bottom, a few miles south of the present site of the modern Council Bluffs. My great object was to find some one who then resided here, and who could from personal recollections settle the question. And such a person I have at last found in Mr. Richard S. Hardin, an old gentleman, son of Indian agent Hardin, who came here with the Pottawattamie Indians in 1838, and who now resides at Nodaway Station in Missouri. In a letter written to me on the 21st of November, 1896, he says:

"he old Fort you wish to know about was built in '42, and vacated in the spring of '43, on account of high water. It was northwest of my old farm 3^ of a mile, in the edge of the timber on the bottom. When they left it they stuck their tents in the hollow near where Judge Casady 's house stands. If there is anything I can give you light on, let me know. I think I will be in Council Bluffs in the spring, and if you will get a reporter, I will answer any questions you may wish to ask, as I think I am the only man living now that can'.

"This statement is reliable and reallj^ settles the question. It corresponds perfectly with the letter of Capt. Burgwin, '43, page 6, in which he stated that his cantonment 'was flooded and that he had commenced removing the public property to the Bluffs, which are about six miles from me'. True, his first letter was written from 'Camp Fenwick near Council Bluffs' evidently referring to the Council Bluffs of the olden time, but that point was less than twenty miles distant, and was the name then applied to all this immediate region. I may add that A. I). Jones, now of Omaha, who in early days resided in Council Bluffs and made the first survey of the town in 1852, insists that 'Camp Fenwick — Fort Croghan' was on the east side of the river not far from the southwest corner of the present corporate limits of the city of Council Bluffs. It was very near, almost the middle of, the then home of the Pottawattamies — the very Indians Captain Burgwin was sent here to protect, although as it turned out, no protection was required.

"This Fort Croghan had no connection in any way with the military buildings, the 'Old Block House in Council Bluff's' at or near the Bryant Springs. That had been built by U. S. troops in 1839. They seem to have left and Capt. Burgwin's Company was probably sent to take their place. Instead, however, of going to the old site, they camped on the bottom near the timber, three or four miles distant in a southwesterly direction from it. Possibly, when I have the interview with Mr. Hardin, this point will also be explained more fully.
Very truly,
  D. C. Bloomer."<br>

----------------------------------------------------------

"Council Bluffs, Nov. 25, 1896.
"Mr. Charles Aldrich.
"Dear Sir :

Referring to my letter of yesterday in relation to the location of Camp Fenwick — Fort Croghan, I would state that I have just received a letter from Mr. Hardin in which he states that the fort instead of being 3 and 14 miles northwest from his old farm, that it was only % of a mile from it. I suspected that this was the fact, and this correction enables us to exactly locate the spot. Mr. Hardin's old farm was in the Ei/s of the SE14 of Section 15-74-44, and % of a mile from it takes us to the £1/2 of Section 10 in the same township and range, and through about the center of this section the line of timber passed. That was the identical spot where the old fort stood. And now I remember that when I first came to the county 41 years ago, there was right there the remains of buildings of some kind, erected in former years. It turns out now that they had been erected by the XJ. S. troops under Capt. Burgwin in the first instance, and perhaps reconstructed by the Mormons.
Yours very truly,
D. C. Bloomer.
"P. S. — I enclose plat of Tp. 74-44, which shows the location."
In that portion of this work relating to the Pottawattamie Indians it is clearly shown that they arrived at or near the present site of the city of Council Bluffs July 28, 1837 ; that the blockhouse was built at that time; that Davis Hardin (father of R, S. Hardin) was not agent for those Indians; that the farm entered by R. S. Hardin in 1854, — undoubtedly the place mentioned by him as "my old farm"', — consisted of Lot 1 (W1/2SW1/4) Sec. 14, and E1/2SE14 Sec. 15, in the township indicated by Mr. Bloomer. On this tract the plat of the United States survey made in 1852 shows three houses, of which two are on the lot 4. It was in one of the latter, according to the writer's recollection, wherein Mr. Hardin resided, about one mile from the old steamboat landing as indicated by the plat of survey.

On the SI/2NE14 Sec. 15 of said township appears the village of ''Council Point", immediately north of and contiguous to the western part of the Hardin farm, and almost exactly three-quarters of a mile from R. S. Hardin's dwelling. In the belief of the writer the site of Council Point, Camp Fenwick or Fort Croghan, was identical. The place was probably renamed because of the fact that it was there that the Pottawattamie Indians of the Iowa region met the Commissioners of the United States June 5, 1846, and signed the treaty ceding their lands, which had actually been negotiated at Washington between the head men of the nation and government officials at a time previous. The buildings erected by Captain Burgwin 's command in 1842 afforded facilities for such transaction not existing at any other place near by.

It is impossible to secure conclusive evidence to support these assumptions; but they do no violence to Mr. Hardin's testimony as furnished by Mr. Bloomer. No point in section ten, Mr. Bloomer's location of Camp Fenwick, could have been reached by traveling only three-quarters of a mile northwest from Mr. Hardin's farm house. The plat of government survey shows only one house on Section 10, and none other is mentioned in the field notes of the survey as being on said section.

When the Mormons reached that locality, June, 1846, they found the little village of Council Point already named, and it was there that their High Council was organized Julj^ 21, by which was accepted the name ' ' Miller 's Hollow ' ' that had attached to the settlement made by the Saints on the site of the present city of Council Bluffs.

Mr. A. D. Jones, who resided at Council Bluffs for some time after the advent of the writer in that vicinity and was well known to him, has been quoted as supporting the claim that Fort Croghan was near the original site mentioned in the article quoted from Annals of Iowa ; it being said that he made a survey of the city in 1852, and is therefore an authority. If he made survey of any part of the city his work was private and not public in character. In a letter dated May 9, 1916, the Council Bluffs City Engineer says:
"There is no evidence in my office to indicate that a survey of the town was made by A. D. Jones prior to the survey made by Tostcvin". (1854.)
Judgo (J. P.) Casady never owned, resided upon or cultivated any farm near the site mentioned in the quoted article other than that embracing the SEi^SEii Sec. 9; SWI/4SW14, E1/2SW14 Sec. 10; NEi^NWii, WVsNWi^ Sec. 15, and EVgNEi^ Sec. 16, T. 74 N., R. 43 W. Six miles due east and across Mosquito creek from the Ft. Croghan site mentioned in the quoted article, and about two miles back of the first bluffs skirting the Missouri river bottom. In 1843 that would have been an inaccessible and undesirable site for a military-encampment dependent upon steamboat transportation for its supplies. The boat landing was more than five miles, air line, from such site, and no practicable route between the points could have been less than eight miles. Mr. Hardin could not have intended to designate the Casady farm as the site where the troops "stuck their tents".

Judge Casady owned and resided for some years in a house in Council Bluffs, near the mouth of what was known in early days as "Duck Hollow", only a short distance from the "Old Block House", It was one of the most prominent houses of that time in the city. Just to the east of it, and immediately north from the old blockhouse, was a broad, almost level plateau, an ideal spot for a military camp such as required by Captain Burgwin's command, and, notwithstanding Mr. Bloomer's positive assertion that the blockhouse and Fort Croghan had "no connection in any way", it very convincingly appears from unpublished letters of the Pottawattamie sub-agent, written in 1842 and 1843, that the dragoons at that time used the blockhouse for storage purposes. (See Mr. Elliott's letter of June 1, 1843, quoted in connection with "Pottawattamie Indians" and "Old Blockhouse", elsewhere in this work.)

It is the belief of the writer that Captain Burgwin and his men, when forced to retire from the bottom, made their encampment upon the plateau described in the preceding paragraph, and that it was the site referred to in the language quoted in Mr. Bloomer's letter to Mr. Aldrich :
"When they left it they stuck their tents in the hollow near where Judge Casady's house stands".
This opinion is corroborated by an unpublished letter from Sub-Agent Elliott, dated June 1, 1843, quoted in the article herein relating to "The Old Blockhouse". True, this site was about five miles from the boat landing, but it was connected therewith by the best and probably only real road in the vicinity at the time, and was at the site of the Caldwell village, then existing, and of the De Smet mission abandoned about two years before. Captain Burgwin who had been acting ad interim Sub-Agent for the Pottawattamies, appears to have turned over the agency effects to Sub-Agent Elliott at that point June 1, 1843.

Captain Burgwin evidently overestimated the distance between Fort Croghan and the bluffs, as there is no point in the Missouri river bottom, above the boat landing as indicated by government survey, in that vicinity where the air-line distance between river and bluffs is six miles. The early settlers made the same error, calling it six miles from Kanesville to the boat landing, whereas it is little more than four miles.

There is no intention to impugn Mr. Bloomer's good faith, nor to question his veracity, bj^ what has been said here ; but simply to differ from some of his inferences, assumptions and conclusions, and to indicate the reasons for such differences. The writer knew Mr. Bloomer well and knows him to have been a conscientious man, but doubts the correctness of his findings upon the evidence considered by him, taken in connection with his knowledge of the locality and the subjects of which he was writing.

On whatever particular sites the "Camp Fenwick" and "Fort Croghan" of Captain Burgwin may have stood, in the vicinity of Council Bluffs, there is ample evidence that neither was in the immediate vicinity of the Council Bluff of Lewis and Clark, nor in any manner connected with Fort Atkinson which was located near the latter. It has been said that there was once a "Fort Croghan" on or near the site of the latter place ; but there appears to be no record evidence to sustain such allegation. Mr. A. D. Jones, at the time Secretary of the Old Settlers' Association of Omaha, addressed a letter of inquiry to Father De Smet, containing several interrogations, to which the eminent missionary, writing from "St. Louis University, December 26, 1867", made separate replies, in part as follows:
"To the best of my knowledge, and assisted by Captain Joseph La Barge, the old explorer of the Missouri river, I will here answer your various questions:

"First, 'Where was old Fort Calhoun located?'

"Fort Calhoun was never located; it took the name of Fort Atkinson, which wjus built on the very spot where the council was held by Lewis and ('lark, and was the higliest and first military post above the mouth of the Nebraska (Platte) river.

"Second, 'Where was old Fort Croghan?'

"After the evacuation of Fort Atkinson or Calhoun, either in 1827 or 1828, or thereabouts, the troops came down and made winter quarters on Cow Island — Captain La Barge states it was called Camp Croghan. The next spring the flood disturbed the soldiers and they came down and established Fort Leavenworth. Colonel Leavenworth was commandant at the breaking up of Fort Atkinson. (See pages 1533-34-35, Chittenden and Richardson's Life, Letters and Travels of Father De Smet, Volume 4, where the letter above quoted is credited to Nebraska Historical Society's Report.)

"Third, 'There is an earthen remain of fortifications on the east bank of Omaha ; do you know who built it?'"

"The remains alluded to must be the site of the old trading post of Mr. Heart. When it was in existence the Missouri river ran up to the trading post. In 1832 the river left it, and since that time it goes by the name of 'Heart's Cut-Off', leaving a large lake above Council Bluffs city."
Assuming this last information to be correct, a starting point is established from which, with other existing evidence, a fairly good inference may be derived respecting the location to which Captain Burgwin removed the government property and his command upon the occasion of the flood in the spring of 1843.

The log of the steamboat "Omega", on a voyage made in 1843, contains the following entries :
"May 9, Tuesday. Passed Trudeau Island, Five Barrels Island, la Calumet, L'Oeil de fer. . . . Went on to L 'Issue, where I put off freight for the sutler and for Captain Burgwin. Set out at 7 P. M. and camped above the bad sandbar, near the marsh at Hart's cut-off at 9 P. M. "May 10, Wednesday. We progressed finely as far as Hart's Bluffs (cotes a Hart), where at 7 A. M., we were summoned by an officer and four dragoons to land. I received a polite note from Captain Burgwin informing me that it was his duty to make an inspection of the boat. We put ourselves to work immediately^ while Mr. Audubon goes to call upon the Captain. They return in about two hours. . . ." (See Chittenden's American Fur Trade of the Far West, Vol. 3, page 988; also Chittenden's History of Early Navigation on the Missouri river. Life and Adventures of JosephLa Barge, Vol. 1, pages 143-144.)
The following extract is from the work last mentioned, and is a part of a very circumstantial account of the inspection of the boat, viz. :
"On the occasion of the voyage of 1843 the agent at Bellevue happened to be absent from his station when the boat arrived. Elated at this unexpected good fortune, Captain Sire lost no time in putting off the freight destined for this point and in getting on his way. He pursued his voyage until nine o'clock that evening, and doubtless felicitated himself that he was out of danger. But it appears that the agent had delegated the function of inspector during his absence to the commander of the United States troops in the vicinity. The boat left her mooring at daylight next morning, but had scarcely gotten under way when a couple of rifle shots were fired across her bow. She brought to at once and made for the shore. There Captain Sire found a lieutenant in charge of a few dragoons, who had come from his camp four miles distant. The young officer came on board and presented to Captain Sire a polite note from Captain Burgwin, commander of the camp, stating that his orders required him to inspect the boat before letting her proceed.

' ' This was like a dash of cold water to the buoyant spirits of Captain Sire, and none the less so to Audubon, to whom, as well as the company, the loss of the liquid portion of the cargo would have been irreparable. The naturalist had a permit from the government to carry with him a quantity of liquor for the use of himself and party, and upon showing his credentials to the young officer he was, to use his own words, 'immediately settled comfortably '. But in the moment of his good fortune he did not forget his companions who were not yet 'settled comfortably'. He understood that time was required to prepare for the approaching function, and he could at least help to secure this time by delaying inspection as long as possible. He accordingly expressed a desire to visit the camp, and the lieutenant detailed a dragoon to accompany him. The great naturalist rode /owr miles to call upon an obscure army officer whom he knew he could see in a short time by waiting at the boat. . . . "
The Audubon referred to in the foregoing excerpts was the well-known and justly celebrated naturalist John James Audubon, and his own story of this occurrence, more interesting for the evidence and information it contains than because of the importance of the transaction above mentioned, is as follows :
"May 9, Tuesday. Another fine day. After running until eleven o'clock we stopped to cut wood. . . . This afternoon we reached B<dk>vue where resides the brother of Mr. Sarpy of St. Louis, as well as the Indian Agent, or as he might be more appropriately called, the Custom House officer. Neither were at home, both away on the Platte river, about 300 miles off. . . . We landed some cargo for the establishment. . . . The store is no great affair, and yet I am told that they drive a good trade with the Indians on the Platte river, and others on this side of the Missouri. We unloaded some freight and pushed off. . . . We soon reached the post of Fort Croghan, so called after my old friend of that name with whom I hunted Raccoons on his father's plantation in Kentucky some thirty-eight years ago, and whose father and mine were well acquainted, and fought together in conjunction with Washington and Lafayette during the Revolutionary War, against 'Merrie England'. Here we found only a few soldiers, dra- goons; their camp and officers having been forced to move across the prairie to the bluffs, five miles. After we had put out some freight for the sutler, we proceeded on until we stopped for the night a few miles above, on the same side of the river. The soldiers assured us that their parade ground and so-called barracks, had been four feet under water, and we saw fair and sufficient evidence of this. . . . We landed for the night under trees covered by muddy deposits from the great overflow of this season. I slept soundly, and have this morning. May 10, written this.

''May 10, Wednesday. The morning was fine, and we were under way at daylight, but a party of dragoons, headed by a lieutenant, had left the camp four miles distcmt from our anchorage at the same time, and reached the shore before we proceeded far; they fired a couple of shots ahead of us, and we brought to at once. The young officer came on board, and presented a letter from his commander. Captain Burgwin, from which we found that we had to have our cargo examined. Our captain was glad of it, and so were we all ; for, finding that it would take several hours, we at once made ready to go ashore. I showed my credentials and orders from the Government, Major Mitchell of St. Louis, etc., and I was therefore immediately settled comfortably. I desired to go to see the commanding officer, and the lieutenant very politely sent us there on horseback, guided by an old dragoon of considerable respectability. I was mounted on a young white horse, Spanish saddle with holsters, and we proceeded across the prairie to- wards the Bluffs and the camp. My guide was anxious to take a short cut, and took me across several bayous, one of which was really up to the saddle ; but we crossed that, and coming to another we found it so miry, that his horse wheeled after two or three steps, whilst I was looking at him before starting myself ; for you all well know that an old traveler is, and must be prudent. We had now to retrace our steps till we reached the very tracks that the squad sent after us in the morning had taken, and at last we reached the foot of the Bluffs, when my guide asked me if I 'could ride at a gallop', to which not answering him, but starting at once at a round run, I neatly passed him ere his horse was well at the pace ; on we went, and in a few minutes we entered a beautiful dell or valley, and were in sight of the encampment. We reached this in a trice, and rode between two lines of pitched tents to one at the end, where I dismounted, and met Captain Burgwin, a young man brought up at West Point, with whom I was on excellent and friendly terms in less time than it has taken me to write this account of our meeting. I showed him my credentials, at which he smiled, and politely assured me that I was too well known throughout the country to need any letters. While seated in front of his tent, I heard the note of a bird new to me, and as it proceeded from a tree above our heads, I looked up and saw the first Yellow-headed Troupial that ever came across my own migrations. . . . The Captain and the doctor, Madison by name, returned with us to the boat. . . . The officers came on board and we treated them as hospitably as we could; they ate lunch with us, and are themselves almost destitute of provisions. . . . The Sioux Indians are great enemies to the Pottawattamies, and very frequently kill several of the latter in their predatory excursions against them. This kind of warfare has rendered the Pottawattamies very cowardly, which Ls quite a remarkable change from their previous valor and daring. . . . We left our anchorage (which means tied to the shore) at twelve o'clock, and about sunset we did pass the real Council Bluff. Here, however, the bed of the river is utterly changed, you may yet see that which is called the Old Missouri. The Bluffs stand, truly speaking, on a beautiful bank about forty feet above the waters and run off on a rich prairie, to the hills in the background to a gentle slope, that renders the whole place a fine and very remarkable spot. . . ." (See Audubon and His Journals, by Maria R. Audubon, with Zoological and Other Notes, by Elliott Coues, Volume 1, pages 477 to 482.)
At the time referred to in the foregoing extracts, from the lower end (or mouth) of the then known "Hart's Cut-off"; that is from the western end of the lake formed by that change in location, the Missouri river flowed in a northwesterly and westerly course through "Cutoff Lake", shown upon recent maps, thence southerly, about as is now does, near the foot of the bluff where stands the city of Omaha, except that at about the site of Soutli Omaha it bore further west, sweeping against the bluff; thence, by a broad curve, southward and ea.sterly, and then Ix^aiing to the north and east, it ^Kissed on the eastern side of the Hardin farm and village of Council Point ; thence, through what is now "Lake Manawa", turning to the east and south, bore southwesterly beyond Trader's Point (Point aux Poulos). So, the Hardin farm and Council Point were within what was locally known later as the "Big Bend". The distance between Bellevue and Hart's Bluffs, by the course of the river, was much greater in 1843 than now.

Beginning on the river bank about a mile south and west from the Hardin farm, a large marsh, with many lateral branches, extended up the river to the shore of the lake formed by Hart's Cut-Off. Its width varied from one-half to one and one-half miles, and covered nearly all of the surface, though there was exposed a high point in the angle between the river and the lake where now is "East Omaha" or "West End", — the name depending upon whether one is in Omaha or Council Bluffs. This was the marsh referred to in the "Omega" log. The location of the "bad sandbar" near this marsh is not deter- minable; Missouri river sandbars are not stable land marks. It is probable that it was not far from Hardin's, possibly near the site of South Omaha. Wlien the writer arrived at Council Bluffs, in 1853, the swamp still existed in diminished area and some of it may be there yet. For many years thereafter — surely up to 1870 — portions of it were known to Council Bluffs sportsmen as "Grassy Slough" and "Smith's Lake".

Upon resuming her voyage above the "bad sandbar" on the morning of May 10, 1843, the "Omega" progressed finely until stopped by the dragoons at 7 : 00 A. M. Giving due consideration to the course of the river, the slow speed of the boat, it may be assumed that the landing of the "Omega" was at the southern bend of the river, below Hart's Cut-Off, near the then foot of the lake, about two miles from the supposed site of Hart's trading house. The distance from this point to Captain Burgwin's camp, as given by La Barge, was four miles, twice repeated, and Audubon says the troopers "had left their camp four miles distant from our anchorage at the same time" that the boat got under way. P>om this "Omega" landing to Casady's farm the distance would have been approximately ten miles by any route then practicable, as may be seen by examination of a sectionized map. The concurrent estimate of time elapsed between Audubon's departure from the boat and his return accompanied by Captain Burgwin and the surgeon is "about two hours", which would indicate that such a distance could not have been covered by his travel to and from the military encampment, even had he not spent some time in talk with the officers and in shooting birds, and had no delay occurred by reason of being required, as Audubon says, to "retrace our steps".

The distance from the point of landing, as here assumed, to the site of the encampment of Captain Burgwin in Council Bluffs, as suggested hereinbefore, would have been substantially four miles — possibly a trifle less. Audubon's description of the ride along the foot of the bluffs, and "on we went, and in a few minutes we entered a beautiful dell or valley, and were in sight of the encampment", tallies perfectly with the situation last suggested. Had they gone to the Casady farm from the point where the steamer was "summoned to land" they would have been obliged to cross the Mosquito creek, probably unbridged, and if they had done this surely Audubon, noted for attention to minute detail, would have mentioned the fact. It might be said, upon the same line of argument, that it is strange that he did not mention Indian creek, coursing through the "beautiful dell or valley" described; but, one familiar with the location there knows that he might not, in fact would not, have seen Indian creek at all. Coming from the halted steamer the course would naturally, in the condition of affairs then existing, have been along the southern margin of the lake, reaching the bluffs at or near the Mynster Spring, thence along the foot of the bluffs and into the dell, following the present Washington Avenue in Council Bluffs to the site of the en- campment, without even noticing the little rivulet which Indian creek then probably was.

Captain Burgwin and his troopers, according to Mr. R. S. Hardin, evacuated their cantonment because of the flood and —
"stuck their tents in the hollow near where Judge Casady 's house stands."
The "Duck Hollow" plateau — on which stood the "Log Tabernacle" of the Mormons — logically meets this description.

The conditions leading to the sending of the command of Captain Burgwin to the Pottawattamie country are referred to in the 1842 report of the Indian agent. (See Sen. Doc. No. 1, 3d Sess., 27th Cong., Vol. 1, page 387.) The agent said:
"There was reason to apprehend, during the last spring, that hostilities would be commenced by the Sioux against the united band of Ottawas, Chippewas and Pottawattamies, on the Missouri, who invited the Delawares to aid in their defence. Prompt and rigorous measures were adopted to prevent this outbreak, which, if it had commenced, would have involved consequences of the most hazardous character to the combatants; would have probably embroiled neighboring tribes, and could have been arrested by the Government only at great cost. A company of dragoons was ordered by your direction to Council Bluffs, and assurances given the threatened party that they would be protected, while the Indians charged with meditating the attack were warned to abstain from it. These measures were effective, and the quiet of the frontier has been preserved."
In addition to Captain Burgwin's report hereinbefore mentioned, and which no doubt formed the basis of the statement of the War Department, dated January 22, 1916, relative to the period during which "Fort Croghan" was in existence (quoted in connection with the account of the Old Blockhouse), testimony by one who was there present showing the date of abandonment is contained in Audubon's journal of the return trip of his party, made by way of the Missouri river in small boats in the months of September and October, 1843. Under October dates appear the following notes, viz. :
"Wednesday, 4th. Cloudy and coldish. Left early and can't find my pocket knife, which I fear I have lost. We were stopped by wind at Cabane Bluffs, about twenty miles above Fort Croghan. . . . Windbound till night, and nothing done.

"Thursday, 5th. Blew hard all night, but clear and beautiful sunrise. Started early, but stopped by wind at eight. Bell, Harris and Squires have started off for Fort Crc^han. As there was every appearance of rain we left at three and reached the fort about half past four. Found all well, and most kindly received. We were presented with some green com and had a quantity of bread made; also bought thirteen eggs from an Indian for twenty-five cents. Honey bees are found here, and do well, but none are seen above this place.

"Friday, 6th. Some rain and thunder last night. A tolerable day. Breakfast at camp and left at half past eight. Our man Michaux was passed over to the officers' boat, to steer them down to Fort Leavenworth, where they are ordered, but we keep in company, and he is to cook for us at night. The whole station is broken up, and Captain Burgwin leaves in a few hours by land with the dragoons, horses, etc. . . . " Inasmuch as Captain Burgwin stated in August that the old encampment would not be fit for reoccupancy, there is no probability that the troops returned there for encampment prior to departure.
Thus ends this story of "Fort Croghan", which the writer believes to contain all attainable facts material to the history of the cantonment, as well as some of his own deductions, inferences and assumptions resting upon apparently strong circumstantial evidence when considered in connection with the conditions existing at the time when the transactions occurred.

Other troops were sent to this region at various times during the occupancy of the southwestern Iowa country by the Pottawattamie Indians, but none other than those mentioned herein and in the several articles comprised in the booklet appear to have been quartered in the immediate vicinity of the site of the present city of Council Bluffs.
