British ships inflict heavy damage on Spanish and French ships in the Second Battle of Algeciras.

The Second Battle of Algeciras was fought on 12 July 1801 between a Royal Navy squadron and a larger Spanish and French squadron in the Gut of Gibraltar during the Algeciras campaign of the war of the Second Coalition. The battle followed the First Battle of Algeciras on 6 July, in which a French squadron anchored at the Spanish port of Algeciras was attacked by a larger British squadron based at nearby Gibraltar. In a heavy engagement fought in calm weather in the close confines of Algeciras Bay, the British force had been becalmed and battered, suffering heavy casualties and losing the 74-gun ship HMS Hannibal. Retiring for repairs, both sides called up reinforcements, the French receiving support first, from the Spanish fleet based at Cádiz, which sent six ships of the line to escort the French squadron to safety.
