Henry's army landed on the north bank of the Seine estuary near to the town of Harfleur (now part of Le Havre). Henry organised the siege of the town and waited for it to fall.

The town held out for five weeks in which time the English soldiers were starting to suffer from disease caught from their camps in the marshes. The people in the town were not doing much better and when it was clear that the town was not going to be rescued, the citizens surrendered. Henry treated the towns people with respect and let them leave.

Henry's plans for invading France had been dented by the time it took to capture Harfleur and the affect of disease on his men. He decided to move his men to Calais which was under English control.

A French fleet laid siege to Harfleur, the French port captured by Henry V, and attempted to get it back. Harfleur was defended by Thomas Beaufort, the earl of Exeter.

An English fleet commanded by John Duke of Bedford attacked and defeated the French blockading the mouth of the Seine who were preventing supplies reaching the English held town of Harfleur. Bedford was the king's brother.

Queen Catherine and her young son landed at Harfleur. From there she travelled to Rouen and then to Vincennes where she met her husband King Henry V. Together they travelled on to Paris. It was around this time that the King's health was failing. ^[1]

The English under the command of Edmund Beaufort, Duke of Somerset, captured the port town of Harfleur on the northern coast of France.
