As raids grew in number, the "high tide"[1] of the Plan of San Diego was August and September 1915.[5] The raids during this period were led by Aniceto Pizana and Luis de la Rosa, well-known residents of South Texas. They were conducted in the style of guerrilla warfare, with the overall purpose of razing U.S. public and private property.[2] The most notable raids of Mexican gangs caused the disruption of communication and transportation in southern Texas.
