HMS Aigle was a 36-gun, fifth-rate frigate of the Royal Navy. Ordered on 15 September 1799 and built at Bucklers Hard shipyard, she was launched 23 September 1801. More than fifty of her crew were involved in the Easton Massacre when she visited Portland in April 1803 to press recruits. Much of her career as a frigate was spent in home waters where she fought the Battle of Basque Roads in 1809; initially providing support to the crews of the fireships, then forcing the surrender of the stranded French ships, Varsovie and Aquilon. Later that year she left The Downs to take part in the Walcheren Campaign where she carried out a two-day long bombardment of Flushing, leading to its capitulation on 15 August.
