35th Infantry Regiment (United States) - World War I

World War I

The 35th Infantry Regiment was stationed at Nogales, Arizona on 27 August 1918, when at about 4:10 pm, a gun battle erupted unintentionally when a Mexican civilian attempted to pass through the border, back to Mexico, without being interrogated at the U.S. Customs house. After the initial shooting, reinforcements from both sides rushed to the border line. Hostilities quickly escalated and several soldiers were killed and others wounded.

The U.S. 35th Infantry border post had about 15–18 men and requested reinforcements from their garrison. When they arrived they requested the Buffalo Soldiers of the 10th Cavalry. The 10th, commanded by Frederick Herman, came to their aid from their camp outside of town. After observing the situation for a few moments, Lt Colonel Herman ordered an attack on the Mexican and German held hilltops overlooking the border town. Defensive trenches and machine gun placements had been seen being dug there in the previous weeks. Herman wanted Americans there before Mexican reinforcements got there.

Under heavy fire, the U.S. 35th Regiment infantry soldiers and dismounted 10th Cavalry troops advanced across the Mexican-American border through the buildings and streets of Nogales, Sonora and up onto the nearby hilltops. This was done while other units of the 35th Regiment held the main line near the border post. About 7:45 pm, the Mexicans waved a large white flag of surrender over their customs building. Lt. Colonel Herman observed and then ordered an immediate cease fire. Snipers on both sides continued shooting for a little while after the cease fire, but were eventually silenced upon orders from their superiors.
