The blockade began on the 27 June and the trenches were opened on the night of the 7/8 July. 100 guns and 60 mortars were in use. Frequent brave and successful sorties by the defenders, as well as the exploding of a large mine under one of the batteries, disrupted the seige. After a series of assaults the French withdrew into the citadel on the 31st July. The citadel was a very hard nut to crack and with the defenders putting up a strong resistance allied progress was slow and costly. By the 31st August the allies were ready to storm the citadel. The Governor, de Surville, sued for terms, these were agreed on the 3rd September and on the 5th the garrison marched out on parole while the allies took possession of the fortress.
