Who defeated Napoleon in 1815 and played a direct role in founding Canada's capital?

Discover Canada ties this question's two facts together in one caption. The guide writes: The Duke of Wellington sent some of his best soldiers to defend Canada in 1814. He then chose Bytown (Ottawa) as the endpoint of the Rideau Canal, part of a network of forts to prevent the U.S.A. from invading Canada again. The same caption finishes with the line that nails down the test answer: "Wellington, who defeated Napoleon in 1815, therefore played a direct role in founding the national capital."

So the man the test wants is the Duke of Wellington. He is the only figure in Discover Canada who is described both as defeating Napoleon in 1815 and as choosing the location that became Ottawa. The earlier name for the spot was Bytown; Discover Canada records the renaming and the strategic logic in the same caption.

The wider War of 1812 backstory makes the choice of Bytown make sense. Discover Canada records that "by 1814, the American attempt to conquer Canada had failed," and that "the British paid for a costly Canadian defence system, including the Citadels at Halifax and Québec City, the naval drydock at Halifax and Fort Henry at Kingston." The Rideau Canal and Bytown were part of that same defence network — Wellington's hand-picked engineers built a route that could move troops without exposure to the U.S. border. The capital city eventually grew up around that strategic engineering project.

The question is testing whether new citizens have noticed that one of the most-cited British military figures in Canadian history is also a hands-on figure in the founding of Ottawa. Discover Canada stitches the two facts together explicitly — Napoleon in 1815 on one side, the choice of Bytown (Ottawa) on the other, with the conclusion that the same man "played a direct role in founding the national capital."

The wrong answer choices come from completely different chapters. Sir John A. Macdonald appears in the Confederation era of 1867, decades after Wellington. Lord Durham is mentioned as "an English reformer sent to report on the rebellions" of 1837–38 and recommended the merger of the two Canadas — not the founding of Ottawa. An American founder belongs to a different country's history, not Discover Canada's.
