In Dong Zhou's war to unite china and 'save' it from the emperor, most of his success came from his battlemaster Lu Bu, the greatest warrior of the age. His effect on moral with his troops, which is a massive influence in warfare, and his demoralisation of enemies, which would often cause enemies to surrender instantly in his presence made him a far greater asset then even Zhou's greatest strategists.
I hope this is applicable to this arguement.
