More than 5,000 troops were under General Miles' command at that time, including elements of the 4th, 6th and 10th Cavalry. He gave the principal pursuit mission to the 4thbecause it was headquartered at Fort Huachuca, the base of operations for the campaign.The Army had permission to go to Mexico in pursuit.Captain Henry Lawton, commanding officer of "B" Troop, 4th Cavalry, was anexperienced soldier who knew the ways of the Apaches.
