The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Silver Star to Second Lieutenant (Coast Artillery Corps) Joseph W. Weeks, United States Army, for conspicuous gallantry and intrepidity in action against the enemy while serving with the 21st Anti-Aircraft Artillery (Automatic Weapons) Battalion (Self Propelled), 25th Infantry Division, in action on of 23 and 24 April 1951, near Unsan-ni, Korea. On that date, although the enemy had secured the commanding ground on the left flank, Second Lieutenant Weeks moved his three half-tracks into blocking position to deny entrance into the valley. After inflicting heavy casualties on the attacking force, he attached all valuable equipment to his vehicles before rejoining the infantry on the new line of resistance. On the following day, when friendly forces were again ordered to disengage, he held his vehicles in place to impede future enemy advances until more tenable positions could be firmly secured. Lieutenant Weeks’ exemplary courage, resolute leadership and unwavering devotion to duty were in keeping with the highest traditions of military service and reflect great credit upon himself, his unit, and the United States Army.
