Hull crosses the Detroit River; his army occupies Sandwich, Upper Canada
In the summer of 1812, the United States had just declared war on Britain and needed to secure its exposed northwestern frontier. William Hull led the newly formed Army of the Northwest from Toledo to Detroit, and briefly pushed his troops across the river into the Upper Canadian settlement of Sandwich, which would later be renamed Windsor, Ontario. The occupation did not last. Within weeks, British General Isaac Brock outmaneuvered Hull, who surrendered his entire force at Detroit on August 16, 1812, without a real fight.
This crossing was the opening move in a war fought to prove the young republic could hold its own frontier and, some hoped, add Canada to it. Hull's collapse days later humiliated Washington and forced President Madison to hand full command to William Henry Harrison, whose subsequent campaign against Tecumseh reshaped American expansion into the Old Northwest for a generation.
QHow did General Isaac Brock manage to bluff William Hull into surrendering an entire army?
Brock had a smaller force than Hull believed, but through swift and decisive action he convinced Hull that resistance was hopeless, leading Hull to surrender his fort, army, and the Michigan Territory at Detroit on August 16, 1812. Hull, already anxious about protecting Detroit's civilians and unsure of his supply lines back to Ohio, convinced himself resistance would end in a massacre. He surrendered on August 16, 1812, handing over his fort, his army, and control of the Michigan Territory to the British.
QWhat happened to the American prisoners taken after the Battle of Frenchtown?
The battle itself, fought January 18 and 22, 1813, ended with 397 Americans dead and 547 captured under James Winchester. The aftermath was worse than the fighting. Native warriors allied with the British killed a number of wounded prisoners where they lay, and many more captives were forced onto a march toward Fort Malden in Ontario and simply left to die along the way. The phrase 'Remember the Raisin,' referencing the River Raisin near Frenchtown, became a rallying cry for American troops for the rest of the war.
QWhy did the U.S. Army expand so dramatically right before the War of 1812 even began?
Congress authorized growing the regular infantry from just seven regiments to twenty-five before the formal declaration of war in June 1812. Lawmakers anticipated a fight over the northwestern frontier and wanted an army in place before hostilities opened rather than scrambling afterward. That buildup produced the force that became the Army of the Northwest under Hull, though the expansion on paper did not translate into readiness in the field, as the Sandwich occupation and Detroit surrender soon proved.
