1346–A. Troops A and B 8th Cavalry, Major Langhorne commanding, four wagons, four automobile trucks left here 7.10 p.m. for Marathon to push south immediately upon arrival there to run down bandits who have recently raided the American side in vicinity Glen Springs and Bouquillas. They have orders to cross to the Mexican side if it becomes necessary in pursuit of bandits and assisting besieged Americans in mines on Mexican side near river.
Colonel Sibley with Troops F and H and machine gun troop 14th Cavalry, pack train from Fort Houston, five automobile trucks and seven wagons will leave Fort Clark with same orders for Marathon either to-night or to-morrow morning and follow Major Langhorne.
As there are no wire communications from Marathon south to points on the river 75 to 90 miles distant arrangements have been made for department signal officer to run ground line from Marathon south.
