On the 16th of August, Major-General Brocke crossed the river a few miles above Detroit without interruption, and immediately marched against the American works with about 700 British troops and 600 Indians. The American troops, advantageously posted and outnumbering the enemy, anxiously awaited the order to fire, when, to their unspeakable astonishment and indignation, they were suddenly ordered to retire within the fort, on the walls of which they beheld a white flag in token of submission. The indignation of the army was so great, that, crowding into the fort without any orders, many it is said wept; others, in stacking their arms, dashed them violently on the ground. Not only the army at Detroit, but the whole territory, with all its forts and garrisons, were surrendered to the British. The British were as much astonished at this surrender as the Americans themselves. General Hull, being exchanged for thirty British prisoners, was arraigned before a court-martial. He was acquitted of treason, but convicted of cowardice and unsoldierlike conduct, and sentenced to death, but was afterwards pardoned by the president in consideration of his revolutionary services. His name, however, was struck from the rolls of the army. Leaving Colonel Proctor to hold possession of the Detroit frontier, Brocke moved off rapidly along the Niagara frontier, from which quarter, also, arrangements had been made, during the summer, for the invasion of Canada, and where a body of troops was collected, under command of Stephen van Rensselaer. Early in the morning of Oct. 13th, a detachment, under Colonel Solomon van Rensselaer, crossed the river and gained possession of the heights of Queenstown, on which was a small battery. At the moment of success the enemy received a reinforcement, under General Brocke, and a long and obstinate engagement ensued, in which the gallant Brocke was killed; and spite of all the exertions General van Rensselaer could make the republicans retired with great loss. A singular circumstance occurred on this disastrous day. General van Rensselaer commanded the militia of New York, in the ranks of which federalist principles were very prevalent; when, therefore, they were needed to support their failing brethren on the other side of the river, they refused to embark, on the plea that they had scruples of conscience against carrying offensive war into the British territories.
