Henry V of England revived the navy, building a number of balingers and "great ships", increasing the fleet from six in 1413 to 39 in 1417/8. These included the 1,400-ton "Grace Dieu" (which still exists, buried in the Hamble estuary), and won victories in the Channel, reaching a high point in 1417 when the French fleet was destroyed. An invasion of France took place in 1415 which led to the capture of Harfleur and the victory at Agincourt. A second invasion, beginning in 1419, led to the conquest of the Channel coast of France, almost eliminating any seaborne threat to England and enabling the running down of Henry's naval forces.
