Without firing a shot, Hull had surrendered Detroit and with it the great territory of Michigan, the most grievous loss of domain that the United States has ever suffered in war or peace.

On the same day Fort Dearborn (Chicago), which had been forgotten by the Government, was burned by Indians after all its defenders had been slain.

These two disasters with the earlier fall of Mackinac practically erased American dominion from the western empire of the Great Lakes.

Visions of the conquest of Canada were thus rudely dimmed in the opening actions of the war.
General Hull was tried by court-martial on charges of treason, cowardice, and neglect of duty.

He was convicted on the last two charges and sentenced to be shot, with a recommendation to the mercy of the President.
