 In July 1861, a small Confederate force of Texans, under the command of Lieutenant Colonel John R. Baylor, captured Mesilla, in the eastern part of the territory.When the town fort was abandoned by its Union garrison, Baylor's force cut off the fleeing Union troops and forced them to surrender.On August 1, Baylor issued a "Proclamation to the People of the Territory of Arizona", which declared that he was taking possession of the territory for the Confederacy, with Mesilla as the capital and himself as the governor.
