HMS St Lawrence – Guide 264

The HMS St. Lawrence was unlike any other warship ever built. Constructed during the War of 1812, she remains the first—and only—first-rate ship of the line to sail exclusively on freshwater.

In this episode of Guide 264, we explore the remarkable story of this forgotten giant: why the Royal Navy built such a massive vessel on Lake Ontario, how she helped secure British naval dominance, and why she never fired a shot in battle.

Discover the history, design, and strategic importance of one of the most extraordinary ships ever commissioned by the Royal Navy.
