The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Major (Cavalry) Thomas John Hall Trapnell (ASN: 0-16782), United States Army, for extraordinary heroism in connection with military operations against an armed enemy while serving as Commanding Officer of the 2d Squadron, 26th Cavalry Regiment, Philippine Scouts, U.S. Army Forces in the Far East (USAFFE), in action against enemy forces at Rosario, La Union, Philippine Islands, on 22 December 1941. During a concentrated fire from enemy tanks and infantry at close range against the rear guard of the 26th Cavalry (Philippine Scouts), Major Trapnell, with one other officer, with total disregard of his personal safety, remained between the hostile troops and his own force, set fire to a truck placed on a bridge, and remained at the bridge exposed to enemy fire until satisfied that the bridge was in flames. Subsequently, Major Trapnell, obtaining a scout car, moved slowly with the rear-most elements of the 26th Cavalry, picking up the wounded, and collecting and giving orders to stragglers. By his heroic actions, Major Trapnell prevented unhindered pursuit by the hostile tanks, saved the lives of a number of wounded, collected many stragglers and set an inspiring example of courage for the entire regiment. His extraordinary heroism, personal bravery and zealous devotion to duty exemplify the highest traditions of the military forces of the United States and reflect great credit upon himself and the United States Army.
