Paul Kagame was still in the United States at the time of the outbreak of war, attending the military training course in Fort Leavenworth. He and Rwigyema had been in frequent contact by telephone throughout his stay in Kansas, planning the final details for the October invasion. At the end of September Kagame informed the college that he was leaving the course, and was settling his affairs ready to return to Africa as the invasion began. The college allowed him to leave with several textbooks, which he later used in planning tactics for the war. When Kagame learned of Rwigyema's death on 5October, he departed immediately to take command of the RPF troops. He flew through London and Addis Ababa to Entebbe Airport, where he was given safe passage by a friend in the Ugandan secret service; the police considered arresting him, but with Museveni out of the country and no specific orders, they allowed him to pass. Ugandan associates drove Kagame to the border and he crossed into Rwanda early on 15 October.
