The remnants of the English army at Formigny took refuge in Caen, where the garrisons of the last Norman strongholds, with the exception of Cherbourg, had also flocked. According to historian Victor-René Hunger, between 3,000 and 4,000 English troops were present in Caen before the siege began. Somerset focused on strengthening Caen's defenses, notably setting fire to and razing part of Bourg-l'Abbé — around the
Abbaye aux Hommes, at the western entrance to Caen — and demolishing the Frileux Bridge, which crosses the
Orne just south of the city, on the road to Rouen and
Paris. On the French side,
Jean de Dunois and
Arthur de Richemont,
Constable of France, organized the siege and gathered considerable forces around Caen, accompanied by the powerful artillery of the brothers
Gaspard and
Jean Bureau. On 5 June, Richemont and
Clermont established themselves in the outskirts of the Abbaye aux Hommes with around 8,200 men, while Dunois, soon joined by King
Charles VII and 600 archers, massed his 5,000 men near the suburb of
Vaucelles, on the right bank of the Orne. A third force positioned itself on the heights around the
Abbaye aux Dames, northeast of the city, and a fourth on the heights north of the city, overlooking the
Château de Caen. Adding the artillerymen, sappers, and carpenters needed for the siege, Victor-René Hunger estimated the number of besiegers at 20,000 men, including 15,000 combatants. To compensate for the destruction of the Frileux Bridge and ensure communication between the two banks of the Orne, a wooden bridge was built upstream from Caen, probably between the villages of
Louvigny and
Allemagne. ==Siege==
