Henry V had reopened the Hundred Years War by invading Normandy in 1415. He had besieged and taken the port of Harfleur, at the mouth of the River Seine, but had suffered heavy losses in doing so. Although his depleted army nevertheless managed to win a famous victory over a much larger French force at Agincourt, the king was forced to withdraw to England to regroup. An English garrison was left behind to hold Harfleur. Over the winter the English raided the surrounding countryside and fought an indecisive skirmish against the French at Valmont.
In the summer of 1416 the French attempted to force the garrison of Harfleur to capitulate by mounting a naval blockade to interdict supplies from England. For this purpose a large French naval force was assembled at Honfleur, the port facing Harfleur across the Seine estuary. Genoese carracks and crossbowmen were hired to reinforce the French. Besides blockading Harfleur, the French ships also ventured across the English Channel to raid the Isle of Wight and menace Portsmouth.
An English fleet was assembled at Southampton to confront the French under the command of John of Lancaster, Duke of Bedford, the king's younger brother. In August 1416 he sallied across the Channel and engaged the French fleet off Harfleur. The English inflicted a heavy defeat on the French, capturing three carracks; a fourth was wrecked while trying to escape.
In the short term, the destruction of the French blockading force frustrated any hope of forcing the capitulation of the English garrison in Harfleur, which in turn ensured that Henry V would have a secure base in Normandy from which to mount his second invasion of the duchy in 1417. This campaign was rapidly successful, resulting in the capture of Caen and Rouen, the conquest of Normandy and ultimately the Treaty of Troyes. In the long run, it ensured that England would enjoy naval supremacy in the English Channel for decades to come .
