Generals with overwhelming assets usually win. Great generals win with the odds against them, but can eventually be defeated by a superior force.
This does not reduce their greatness.
Look up the Seige of Jadotville. They lost, but they put up one h3ll of a defense.
No that would be the General Lee. Pickett lost 49% of his attacking force at Cemetary Ridge. “Picket’s Charge” was a replay of Lee’s assault at Malvern Hill. He ignored the old military dictum “never attack a superior enemy, up hill, when the enemy is expecting the attack. Both the Maryland campaign and the Pennsylvania Campaign ended in failure. Neither produced the results that the Army Commander planned to achieve.
