An explosion of badly degraded propellant charges on board the French battleship Liberté detonates the forward ammunition magazines and destroys the ship.

Liberté was a pre-dreadnought battleship built for the French Navy in the mid-1900s. She was the lead ship of the Liberté class, which included three other vessels and was a derivative of the preceding République class, with the primary difference being the inclusion of a heavier secondary battery. Liberté carried a main battery of four 305-millimeter (12 in) guns, like the République, but mounted ten 194 mm (7.6 in) guns for her secondary armament in place of the 164 mm (6.5 in) guns of the earlier vessels. Like many late pre-dreadnought designs, Liberté was completed after the revolutionary British battleship HMS Dreadnought had entered service, rendering her obsolescent.
