Although Talbot is generally remembered as a great soldier, some have raised doubts as to his generalship. In particular, charges of rashness have been raised against him. Speed and aggression were key elements in granting success in medieval war, and Talbot's numerical inferiority necessitated surprise. Furthermore, he was often in the position of trying to force battle on unwilling opponents. At his defeat at Patay in 1429 he was advised not to fight there by Sir John Fastolf, who was subsequently blamed for the debacle, but the French, inspired by Joan of Arc, showed unprecedented fighting spirit – usually they approached an English position with trepidation. The charge of rashness is perhaps more justifiable at Castillon, where Talbot, misled by false reports of a French retreat, attacked their entrenched camp frontally, facing wheel to wheel artillery.
