This engraving, circa 1836, shows American troops (shown in blue uniforms) crossing the Niagara River and landing at Queenston. British and Canadian troops (shown in red uniforms) under General Isaac Brock came out of Newark (now Niagara-on-the-Lake) and drove the Americans back to the heights. Seeing this, New York militiamen still on the American shore refused to cross into Canada to reinforce the troops there. General Brock was killed during an advance towards the doomed Americans on the heights.
