French ship Indivisible (1799)

Indivisible was a Tonnant class 80-gun ship of the line of the French Navy.

Originally named the Indivisible in 1793, she was commissioned in Toulon on 23 September 1800. On 5 February 1803, she was renamed Alexandre, and recommissioned in Brest under Captain Leveyer.

In December, under Captain Garreau, she was part of Corentin Urbain Leissègues's squadron bound for San Domingo. She took part in the subsequent Battle of San Domingo, where she was badly damaged by the fire of HMS Superb, which left her adrift, her rigging shot off and her rudder destroyed. She was taken by HMS Spencer.

From 1808, the Royal Navy used her as a gunpowder hulk in Plymouth. Indivisible was eventually broken up in 1822.
