president. He commanded the national guard raised by Napoleon. After a brief return to his regiment Napoleon was promoted to First Lieutenant and came home again on leave in 1791. All officers were recalled from leave in 1792, intervention threatened and war with Austria (Marie-Antoinette's homeland) began. Napoleon returned to Paris for review, was exonerated, then promoted to Captain and given leave to escort his sister, a schoolgirl, back to Corsica at state expense. His family was prospering; his estate increased. Napoleon became a Lieutenant-Colonel in the Corsican National Guard. Paoli sent him off on an expedition to Sardinia, ordered by France, under Paolis's nephew but the nephew had secret orders from Paoli to make sure the expedition failed. Paoli was now a conservative, opposing the execution of the king and supporting an alliance with Great Britain. Returning from Sardinia Napoleon with his family and all his supporters were instrumental in getting Paoli denounced at the National Convention in Paris in 1793. Napoleon earned the hatred of the Paolists by pretending to support Paoli and then turning against him (payment, one supposes, for Sardinia). Paoli was convicted in absentia, a warrant was issued for his arrest (which could not be served) and Napoleon was dispatched to Corsica as Inspector General of Artillery to take the citadel of Ajaccio from the royalists who had held it since 1789. The Paolists combining with the royalists defeated the French in two pitched battles and Napoleon and his family went on the run, hiding by day, while the Paolists burned their estate. Napoleon and his mother, Laetitia, were taken out by ship in June 1793, by friends while two of the girls found refuge with other friends. They landed in Toulon with only Napoleon's pay for their support. The Bonapartes moved to Marseille but in August Toulon offered itself to the British and received the protection of a fleet under Admiral Hood. The Siege of Toulon began in September under revolutionary officers mainly untrained in the art of war. Napoleon happened to present socially one evening and during a casual conversation over a misplaced 24-pounder explained the value of artillery. Taken seriously he was allowed to bring up over 100 guns from coastal emplacements but his plan for the taking of Toulon was set aside as one incompetent officer superseded another. By December they decided to try his plan and made him a Colonel.
