Quibéron mutinies

The Quibéron mutinies were cases of major mutinies that occurred in the Brest squadron of the French Navy in September 1793, at the height of the Reign of Terror. They offered reasons and pretexts for the Jacobins to purge the Navy of most of its officers who were of noble extraction. The event was interpreted as both a culmination of the disorganisation of the French Navy from 1790, and a cause of its disorganisation in the following years.

After several months of cruise, a large squadron stationed off Quiberon mutinied and demanded to sail back to harbour. The mutineers took pretext of the surrender of Toulon to the Anglo-Spanish, arguing that their presence in Brest was required to prevent Royalist conspirators from surrendering Brest as well; in the face of overt rebellion, and incapable of maintaining discipline and order, Vice-admiral Morard de Galles took upon himself to order the return to Brest.

In consequence, Représentant en mission Jean Bon Saint-André, the naval expert of the National Convention, was called to Brest to reestablish order and reorganise the Navy. The following repression claimed relatively few lives in the Navy, but argued of a putative Royalist plot by Navy officers loyal to the Ancien Régime to explain the incident. In consequence, a number of officers were relieved of duty and arrested, including two admirals.

The collapse of the French absolute monarchy with the French Revolution had an important impact on the French Navy: the Navy was strongly linked to the monarchy by its officer corps, largely recruited from the nobility, and trained in highly technical disciplines; it was also enormously dependant on funds and supplies to maintain ships and crews. The collapse of Royal power triggered a shift of authority towards local governments, the revolutionary municipalities. These municipalities were both the rivals of the former detentors of authority under the Ancien Régime, and potential rivals to the central power in Paris.
