The expeditionary force built at Camp Vickers one mile south of Pandapatan, and Davis assigned Pershing to Baldwin's command as an intelligence officer and as director of Moro affairs. As director, 'Black Jack' Pershing had a veto over Baldwin's movements, which was an unstable arrangement. This arrangement was tested when survivors of Pandapatan began building a Cotta at Bacolod. Baldwin wanted to move on the hostile Moros immediately, but Pershing warned that doing so could create an anti-American coalition of the surrounding Datus, while some patient diplomacy could establish friendly relations with most of the Moros, isolating the hostile minority. Baldwin grudgingly agreed. On June 30, Pershing assumed command of Camp Vickers, and Baldwin returned to Malabang. A command the size of Camp Vickers would normally have gone to an officer with the rank of Major, and a careful shuffling of personnel would be required to ensure that reinforcements to the Camp did not include officers that were senior to Pershing.
