Colossus fought at Trafalgar under Captain James Nicoll Morris, in Collingwood's lee column. After sustaining fire from the enemy fleet, she eventually ran by the French Swiftsure, 74, and became entangled with Argonaute, 74. Towards the end of the exchange of fire between the two ships, Captain Morris was hit by a shot from one of Argonaute's guns, just above the knee. Argonaute broke free from Colossus after this, whilst the British ship was engaging both Swiftsure and the Spanish Bahama, 74, on her other side. Bahama surrendered when Colossus brought down her main mast, and Swiftsure did likewise after combined fire from Colossus and  brought down her main and mizzen masts. War of 1812
