“(1970) A combined U.S. Air Force and Army team of 40 Americans – led by Army Colonel “Bull” Simons – conducts a raid on the Son Tay prison camp, 23 miles west of Hanoi, in an attempt to free between 70 and 100 Americans suspected of being held there.

The raid was accomplished in a superb manner and all Americans returned safely, but it was learned later that the prisoners had been moved elsewhere in July. Despite that disappointment, the raid was a tactical success and sent a message to the North Vietnamese that the United States was capable of inserting a combat force undetected only miles from their capital.” – HISTORY.com
