When the French National Convention declared war on Britain on 1 February 1793, both powers held colonies in India. British forces, recently engaged in the Third Anglo-Mysore War, were far stronger than the French garrison at Pondicherry. News of the war took five months to reach the Indian Ocean, but British forces mobilised quickly and seized all French Indian ports except Pondicherry.
On 1 August 1793, Colonel John Braithwaite began a siege of Pondicherry while Rear-Admiral William Cornwallis imposed a naval blockade. British troops dug trenches and constructed batteries under heavy French fire over several weeks. Twenty days after the city was cut off, Braithwaite opened a bombardment of the defences; within hours French commander Prosper de Chermont requested a truce and surrendered unconditionally the following morning.
The fall of Pondicherry effectively ended French military presence in India during this phase of the Revolutionary Wars. The French garrison, outnumbered and isolated from any relief by the distant French frigate squadron at Île de France, could not resist the British assault. Britain gained full control of French India's coast, removing France as a colonial rival on the subcontinent for the duration of the conflict.
