The English army landed on the coast of Normandy near
Deauville. Henry's plan was to capture and garrison the major cities and towns of Lower Normandy, before moving on towards Paris. His first objective was the city of Caen, the second largest in Normandy with a population of up to 40,000. The French garrison began demolishing buildings outside of the walls to avoid giving cover to the attackers, however two large
monasteries were still being prepared for demolition when the English
vanguard, led by
Thomas of Lancaster, Duke of Clarence, arrived. Clarence took over the
Abbey of Sainte-Trinité as his headquarters. A story says that a monk from the other monastery, the
Abbey of Saint-Étienne or
Abbaye aux Hommes ("Men's Abbey"), came to Clarence at night, begged him not to allow the French troops to destroy the church and offered to show him a way over the abbey walls. The abbey, which had a commanding view over the town, was captured and Henry later installed guns on the roof. with an artillery barrage on the lower town. The English
cannon were so large that the shock of firing broke the abbey windows. The larger guns fired solid stone balls or hollow iron shells filled with combustible material, while the smaller guns fired showers of lead shot. In the course of the siege, an English knight, Sir Edward Sprenghose, managed to scale the walls, but fell and was burned alive by the city's defenders, who threw burning straw down on him.
Thomas Walsingham wrote that this was one of the factors in the violence with which the captured town was sacked by the English. Clarence's men broke through first, a soldier called Harry Ingles being the first over the wall. After fierce house to house fighting led by
Richard Beauchamp, 13th Earl of Warwick shouting "A Clarence, a Clarence, a
St George!", were able to clear the defenders from the ramparts and open the gates for the king's men to enter. The rules of war at that time meant that a garrison that refused to surrender was at the mercy of the successful attackers. English chroniclers are at pains to praise Henry, who ordered that no women or priest should be harmed or churches plundered; however, his men forced anyone they could find into the market place, where they massacred between 1,800 and 2,000 people. According to one account, Henry ordered a halt to the killing when he came across the headless body of a woman with a baby in her lap. His soldiers were then turned loose to pillage the town. ==Aftermath==
