Repeated sacking

In 1338 a French fleet led by Nicholas Béhuchet arrived in Portsmouth Harbour flying English flags before anyone realised that they were a hostile force. The French burned down most of the buildings in the town; only the local church and Domus Dei survived. The population was subjected to rape and slaughter. As a result of this, King Edward III gave the remaining townsfolk exemption from national taxes so that they could afford to rebuild the town. Only ten years after this devastation, the town for the first time was struck by the plague known as the Black Death. In order to prevent the regrowth of Portsmouth as a threat, the French again sacked the city in 1369, 1377 and 1380. This directly resulted in the first permanent fortifications in Portsmouth, the Round Tower at the harbour mouth.
