cannonade was returned from seven 24-pounders, but the British general, perceiving that little effect was produced by either fire, gave orders that his should cease.  The troops retired to their bivouac and lay on their arms, with orders to cross the strait, or river, which is here about three-fourths of a mile in width, on the following morning.  Accordingly, at the first blush of dawn, on Sunday, the 16th of August, when the fire from the British battery was resumed, 330 regulars and 400 militia were embarked, with five pieces of light artillery, in boats and canoes of every description, and soon effected a landing without opposition, near Springwell, four or five miles below Detroit.  About 600 Indians, under Colonel Elliott, had crossed the river during the night, and were ordered to be so placed as to take the enemy in flank and rear, should he attempt to oppose the landing.  The white troops marched towards the fort, while the Indians moved through the woods, and covered the left flank, the right resting upon the river, and protected by the Queen Charlotte, colonial vessel of war.  The enemy’s effective force was estimated at nearly 2,500 men, and, supported as they were by a neighbouring fortress, it required no little daring to pursue them on their own ground with such unequal numbers.  Contrary to Major-General Brock’s expectation, the Americans abandoned a favorable position, strengthened by pickets and two 24-pounders, and retreated into the fort on the advance of the British, who halted in a ravine within a mile, and, discovering the weakness of the works on the land side, prepared for its assault.  While the various columns were forming for that purpose, a flag of truce, borne by Captain Hull, was unexpectedly seen emerging from the fort,—­Lieut.-Colonel M’Donell and Captain Glegg accompanied him back; and shortly after the British troops marched in with Major-General Brock at their head, the American general having assented to a capitulation, by which the Michigan territory, Fort Detroit, with thirty-three pieces of cannon,[68] the Adams vessel of war,[69] and about 2,500 troops, including one company of artillery, some cavalry, and the entire 4th U.S. regiment of infantry, with a stand of colours, were surrendered to the British arms.  An immense quantity of stores and the military chest were also taken; and as there was a great deficiency of arms in the Upper Province wherewith to equip the militia, the 2,500 stand of American became a valuable acquisition.  To this surrender the after preservation of Upper Canada, at least, may in a great measure be ascribed, as it caused a delay of nearly a whole year in the meditated invasion,[70] and secured the support of some of the Indian tribes, who were hesitating as to the side they should espouse.  It was the more fortunate that Major-General Brock acted with so much promptitude and vigour, because large reinforcements were on their way to General Hull; and not only would that officer’s reverse otherwise have been spared, but the western districts of Upper Canada would probably have fallen before the overwhelming numbers which would soon have been brought against them.
