Topolobampo, December 21, 1915.
M–3240. Indians again raiding Yaqui Valley, attacking settlers at Ontagota and the experimental station at San Pedro. Reported that troops and people were deserting Ontagota and that General Obregon has ordered six hundred cavalry from Esperanza who should arrive at Ontagota between 8 and 12 tonight. One thousand troops have left Magdalena enroute to Yaqui Valley via Guaymas and it is hoped that they will arrive in the valley tomorrow. I do not understand that Americans are leaving the valley. Am I to land troops if General is willing? Immediate answer requested.
