Buenos Ayres (Napoleonic Wars).
This city was captured June 27, 1806, by a coup de main, by a British force, 1,700 strong, under General Beresford, aided by a small squadron under Sir Home Popham. Beresford, however, was not strong enough to hold the place, and before reinforcements could arrive he was defeated by the South Americans under General Liniers, with a loss of 250 killed and wounded, and compelled to surrender with his whole force.
