With those two potential enemies gone, and after two years of patient preparation following the Battle of Agincourt, Henry renewed the war on a larger scale in 1417. After [[Siege of Caen (1417)|taking Caen]], he quickly conquered Lower Normandy and [[Rouen]] was cut off from Paris and besieged. [[Siege of Rouen (1418-1419)|This siege]] has cast an even darker shadow on the reputation of the king adding to the loss of honor following his order to slay the French prisoners at Agincourt. The leaders of Rouen, who were unable to support and feed the women and children of the town, forced them out through the gates believing that Henry would allow them to pass through his army unmolested. However, Henry refused to allow this, and the expelled women and children died of starvation in the ditches surrounding the town. The French were paralysed by the [[Armagnac–Burgundian Civil War|disputes]] between the [[Burgundian (party)|Burgundians]] and the [[Armagnacs]]. Henry skillfully played one against the other without relaxing his warlike approach.<ref name=EB1911/>

In January 1419, Rouen fell.<ref name=EB1911/> Those Norman French who had resisted were severely punished: [[Alain Blanchard]], who had hanged English prisoners from the walls of Rouen, was summarily executed; Robert de Livet, [[Rouen Cathedral|Canon of Rouen]], who had [[excommunicated]] the English king, was packed off to England and imprisoned for five years.<ref>{{cite book |last=Kingsford |date=1901 |first=C. |title=Henry V: The Typical Mediæval Hero |url=https://archive.org/details/henryvtypicalmed00kinguoft |publisher=GP Putnam's Sons |author-link=Charles Lethbridge Kingsford}}</ref>

By August, the English were outside the walls of Paris. The intrigues of the French parties culminated in the [[assassination of John the Fearless]], [[Duke of Burgundy]], by the [[Dauphin of France|Dauphin]] [[Charles VII of France|Charles]]'s partisans at [[Montereau-Fault-Yonne]] on 10 September. [[Philip the Good]], the new duke, and the French court threw themselves into Henry's arms. After six months of negotiation, the [[Treaty of Troyes]] recognised Henry as the heir and regent of France.<ref name=EB1911>{{EB1911 |last=Kingsford |first=Charles Lethbridge |display=Henry V. |volume=13 |pages=284–285 |wstitle=Henry V. of England |author-link=Charles Lethbridge Kingsford |inline=1}}</ref> On 2 June 1420 at [[Troyes Cathedral]], Henry married Catherine, daughter of Charles VI. They had only one son, [[Henry VI of England|Henry]], born on 6 December 1421 at [[Windsor Castle]]. From June to July 1420, Henry V's army besieged and took the military fortress castle at Montereau-Fault-Yonne close to Paris. He besieged and captured [[Melun]] in November 1420, returning to England shortly thereafter. In 1428, Charles VII retook Montereau, only to see the English once again take it over within a short time. Finally, on 10 October 1437, Charles VII was victorious in regaining [[Montereau-Fault-Yonne]].

While Henry was in England, his brother Thomas, Duke of Clarence, led the English forces in France. On 22 March 1421, Thomas led the English to a disastrous defeat at the [[Battle of Baugé]] against a Franco-Scottish army. The duke was killed in the battle. On 10 June, Henry sailed back to France to retrieve the situation. It was to be his last military campaign. From July to August, Henry's forces besieged and captured [[Dreux]], thus relieving allied forces at [[Chartres]]. On 6 October, his forces [[Siege of Meaux|laid siege]] to [[Meaux]], capturing it on 11 May 1422.
