Hull reached Detroit on 5 July, where he was reinforced by detachments of Michigan militia, including the 140 men of the Michigan Legionary Corps, which Hull had established in 1805. The American army was short of supplies, especially food, as Detroit provided only soap and whiskey. Nevertheless, Eustis urged Hull to attack Amherstburg. The fort there was defended by 300 British regulars, mainly from the 41st Regiment of Foot, 400 Indians, and some, principally Essex, militia. The post's commander was Colonel St. George, who was later superseded by Colonel Henry Procter of the 41st. Hull was not enthusiastic and wrote to Eustis that "the British command the water and the savages." Nevertheless, his army crossed into Canada on 12 July. He issued several proclamations which were intended to induce Canadians to join or support his army while some of his mounted troops raided up the Thames River as far as Moraviantown. These moves discouraged many of the militia from opposing his invasion, but few of the inhabitants of the region actively aided him, even those who had recently moved from the United States.
