June 17th.--Col. M'Arthur's regiment again went forward;--on the 20th the army followed. An extensive swamp we had to pass through, called the Black Swamp, rendered it impossible to carry our baggage on waggons; it was therefore found necessary to transfer the flour to pack-horses, which was put up in bags for the purpose. Much rain having previously fallen, we had to wade for whole days through mud and water, tormented in the extreme both night and day by the stings of the innumerable musquetos and knats. The water we drank could only be obtained from holes made by the pioneers in advance, or from places where trees had been torn up by the roots. It was thought that the Indians might cause us some trouble on our march through this forest, and a temporary breast-work of felled trees was erected each day on encamping--however, we received no annoyance from any enemy, during our march to the Miami rapids, where we arrived on the 29th, and found Col. M'Arthur encamped on a beautiful plain on the bank of the river. On the opposite shore, we were told, was the famous spot where, on the 20th Aug. 1794, Gen. Wayne gained an important victory over a body of about 2000 Indians. July 1--We crossed the river, and the 4th Regt. were mustered, when we marched a few miles through a small village and encamped. Here the General chartered a small schooner to take the sick and baggage, and hospital stores of the army to Detroit, with Lieut. Gooding of the 4th regiment, and lady, and the ladies of Lieuts. Bacon and Fuller, and two Sergeants, Jennison and Forbush, and about thirty privates.--These were all taken by the British brig Hunter, at the mouth of Detroit river, and which was the first notice these people had of the declaration of war.--The capture of this vessel was truly unfortunate in its consequences to the American army, as many papers of great importance, relative to our future operations, fell into the hands of the enemy, besides the private baggage of some of the officers of the army. [Illustration: ANTHONY WAYNE] Mrs. Bacon and Mrs. Fuller were sent to Detroit by a flag of truce immediately after the schooner was taken.--Mrs. Gooding preferred remaining at Malden, with her husband, who was then seriously indisposed.
