Consul Simpich to the Secretary of State.
Nogales, December 22, 1915.
Referring to my December 21: Obregon instructed his agent here to inform us that active campaign against Yaquis started last night; that Generals Dieguez, Flores, Martinez, Manso and Gomez taking field with ten thousand troops, working from Guaymas and Esperanza as bases. Trains commandeered and troops enroute various points in Valley. Large quantities munitions being shipped from here south. Movement is businesslike and hope is entertained that campaign may result ultimate control of Yaqui problem. Far as learned no Americans killed. Late Indian raids through property, destruction believed considerable.
