Scuttled

Scuttling is the act of deliberately sinking a ship by allowing water to flow into the hull. This can be achieved in several ways—valves or hatches can be opened to the sea, or holes may be ripped into the hull with brute force or with explosives. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force; as a blockship to restrict navigation through a channel or within a harbor; or to provide an artificial reef for divers and marine life.

The Spaniard conquistador Hernán Cortés, who led the first expedition that resulted in the fall of the Aztec empire, ordered his men to strip and scuttle his fleet to prevent the secretly planned return to Cuba by those loyal to Cuban Governor Diego Velázquez de Cuéllar. Their success would have halted his inland march and conquest of the Aztec Empire.

HMS Sapphire was a 32-gun, fifth-rate sailing frigate of the Royal Navy in Newfoundland Colony to protect the English migratory fishery. The vessel was trapped in Bay Bulls harbour by four French naval vessels led by Jacques-François de Brouillan. To avoid capture, the English scuttled the vessel on 11 September 1696.

The British sank one ship on October 10, 1781 to prevent it from getting captured by the French fleet.
