The President of the United States of America takes pleasure in presenting the Navy and Marine Corps Medal to Lieutenant Keith G. Nichols, United States Navy, for heroic conduct in enemy controlled waters during World War II. By skillful performance of duty as Assistant Approach Officer aboard a United States Submarine, he contributed to the successful completion of four war patrols, resulting in the sinking of 61,677 tons of enemy shipping and the damaging of an additional 30,210 tons. Despite poor visibility, he sighted an enemy submarine and conned his vessel into position from which a damaging attack was made.
