To be sure, the individual ingredients alone cannot explain his success. The same ingredients were available to his successors. Yet no one (in Burma or elsewhere in the successor states of his empire) could put them together. For example, he raised upwards of 60,000 to 70,000 men for his major campaigns. His Toungoo successors raised a third at most. It was not until the early Konbaung kings that the army again raised nearly as many men. Harvey notes: "From his teens until his death, he was constantly in the field, leading every major campaign in person. The failure of other kings who attempted the same conquests is the measure of his ability."
