for the St. Lawrence River and Great Lakes trade, of which ten operated on Lake Ontario. The single largest engine foundry in British North America before 1838 was the Eagle Foundry of Montreal, founded by John Dod Ward in the fall of 1819 which manufactured 33 of the steam engines. The largest Upper Canadian engine manufacturer was Sheldon & Dutcher of Toronto, who made three engines in the 1830s before being driven to Bankruptcy by the Bank of Upper Canada in 1837. The major owner-operators of steamships on Lake Ontario were Donald Bethune, John Hamilton, Hugh Richardson, and Henry Gildersleeve, each of whom would have invested a substantial fortune. Roads Besides marine travel, Upper Canada had a few Post roads or footpaths used for transportation by horse or stagecoaches along the key settlements between London to Kingston. The Governor's Road was built beginning in 1793 from Dundas to Paris and then to the proposed capital of London by 1794. The road was further extended eastward with new capital of York in 1795. his road was eventually known as Dundas Road. A second route was known as Lakeshore Road or York Road which was built from York to Trent River from 1799 to 1900 and later extended eastwards to Kingston in 1817. This road was later renamed as Kingston Road. United States relations War of 1812 (1812–1815) During the War of 1812 with the United States, Upper Canada was the chief target of the Americans, since it was weakly defended and populated largely by American immigrants. However, division in the United States over the war, a lackluster American militia, the incompetence of American military commanders, and swift and decisive action by the British commander, Sir Isaac Brock, kept Upper Canada part of British North America. Detroit was captured by the British on 6 August 1812. The Michigan Territory was held under British control until it was abandoned in 1813. The Americans won the decisive Battle of Lake Erie (10 September 1813) and forced the British to retreat from the western areas. On the retreat they were intercepted at the Battle of the Thames (5 October 1813) and destroyed in a major American victory that killed Tecumseh and broke the power of Britain's Indian allies. Major battles fought on territory in Upper Canada included: Battle of Queenston Heights, 13 October 1812 Burning and Battle of York, 27 April 1813 Battle of Fort
