Blames Mexican Troops.

New York Times 100 years ago today, March 6, 1913:
Gen. Bliss Reports That Ours Gave Provocation in Border Fights.
    WASHINGTON, March 5.— Mexican troops were responsible for the latest border fight near Douglas, Ariz., with soldiers of the Ninth Cavalry, by firing the first shot, according to a report to-day from Brig. Gen. Bliss at Fort Sam Houston. Gen. Bliss says Col. Guilfoyle reported that an armed body of Mexicans, apparently Yaquis, moved out of Agua Prieta yesterday morning, deployed, and fired a lew shots at a detached post about 1,000 yards south of the camp on the boundary.
    An American machine gun replied with five shots, and the Mexicans retired toward Agua Prieta. Col. Guilfoyle made no mention of any casualties, but said he had two troops with a machine gun on observation at the points where the trouble occurred. He added no cause was known for the attack. as no provocation was given by the Americans.
    Detailed reports which have reached the State Department of the first collision between American troops and Mexicans near Douglas make it appear it was the work of Maderistas, and that, although the Mexican Federal forces were not at first involved, they were drawn into the long-range duel. Only one person was wounded.
