Anglo-French War of 1542–1546

Henry VIII entered war against France in alliance with Emperor Charles V and campaigned around Boulogne. The conflict placed heavy financial pressure on the English crown and required extensive mobilisation on land and at sea.

France responded in 1545 with a major fleet and an attempted invasion of southern England. Fighting around the Solent and Isle of Wight failed to secure a French foothold, although the English warship Mary Rose sank during the naval action.
