On the 3rd of July, Lieutenant Rolette, commanding the armed brig _Hunter_, at ten o'clock in the forenoon, succeeded in capturing the _Cayuga_ packet, bound from the Miami river to Detroit, with troops, and laden with the baggage and hospital stores of the American army. He made a dash at the _Cayuga_ in his barge, and, with only six men, secured her.
Colonel Proctor now assumed the offensive. He sent Captain Tallon, on the 5th of August, with an inconsiderable detachment of the 41st regiment, and a few of the many Indians, who were flocking to his standard, to Brownstown, a village opposite Amherstburgh. Captain Tallon energetically carried out his instructions, by surprising and routing more than two hundred of the Americans, who were under the command of Major Vanhorne. The captured detachment were on their way from Detroit to the river Raisin, in the expectation of meeting there a detachment of volunteers, from Ohio, under Captain Burr, with a convoy of provisions for the army. General Hull's despatches fell into the hands of the captors. The deplorable state of the American army was disclosed, and, without loss of time, Colonel Proctor sent over a reinforcement, consisting of one hundred men, of the 41st regiment, with some militia and four hundred Indians, under the command of Major Muir, their landing being protected by the brig _Hunter_. Nor were the American General's misfortunes yet to be ameliorated. While these things were taking place, a despatch reached him from the officer commanding the Niagara frontier, intimating that his expected co-operation was impossible. On every side, General Hull was being hemmed in. His supplies had been cut off. Defeat had befallen him so far and death, sickness, fatigue and discomfiture had its depressing effect upon his soldiery. There was no insurrection in Canada. The people of the backwoods had not the slightest desire to be territorially annexed to that country over which the standard of union had waved for thirty years. On the contrary, they were bent upon doing it as much mischief as possible. They had no idea of transferring their allegiance to a power who had visited them with the miseries of war, for no fault of theirs. Hull was dismayed. When it was announced that General Brocke was advancing against him, he sounded a retreat. Unwilling that his fears should be communicated to the troops under him, General Hull retreated ostensibly with the view of concentrating the army. After he had re-opened his communications with the rivers Raisin and Miami, through which the whole of his supplies came, he was to resume offensive operations. That time never came. On the 8th of August, Sandwich was evacuated. Two hundred and fifty men only were left behind, in charge of a small fortress, a little below Detroit. When again in Detroit, General Hull sent six hundred men under Colonel Miller, to dislodge the British from Brownston. Major Muir, who commanded at Brownston, instead of waiting for the attack, quixotically went out to meet his adversaries. The two opposing detachments met at Maguago, a kind of half way place, where a fight began. It was of short duration, but, considering the numbers engaged, was sanguinary. Seventy-five of the Americans fell, and the British were compelled, though with inconsiderable loss, to retreat. On the water as on the land, the chief mischief fell upon the Americans. Lieutenant Rolette, with the boats of the _Queen Charlotte_ and _Hunter_, intercepted, attacked, and captured eleven American batteaux and boats, which were _en route_ for Detroit, under the escort of two hundred and fifty American soldiers, marching along the shore, the boats and batteaux having on board fifty-six wounded Americans and two English prisoners.
