Louis Hugh Wilson Jr. (February 11, 1920 – June 21, 2005) was a United States Marine Corps four-star general and a World War II recipient of the Medal of Honor for his actions during the Battle of Guam.

In March 1956, Wilson was assigned to Headquarters Marine Corps (HQMC), serving two years as head, Operations Section, G-3 Division.

As assistant chief of staff, G-3, 1st Marine Division, he was awarded the Legion of Merit and the Republic of Vietnam Cross of Gallantry with Gold Star.

Promoted to brigadier general in November 1966, he was assigned to HQMC in January 1967, as legislative assistant to the commandant of the Marine Corps until July 1968.

During that tour, Wilson was presented the Korean Order of National Security Merit, Guk-Seon Medal, 2d Class and the Philippine Legion of Honor (Degree of Commander) for his service to those countries.

Ordered to take that portion of the hill within his zone of action, Captain Wilson initiated his attack in midafternoon, pushed up the rugged, open terrain against terrific machine-gun and rifle fire for 300 yards and successfully captured the objective.

Promptly assuming command of other disorganized units and motorized equipment in addition to his own company and one reinforcing platoon, he organized his night defenses in the face of continuous hostile fire and, although wounded three times during this five-hour period, completed his disposition of men and guns before retiring to the company command post for medical attention.

Shortly thereafter, when the enemy launched the first of a series of savage counterattacks lasting all night, he voluntarily rejoined his besieged units and repeatedly exposed himself to the merciless hail of shrapnel and bullets, dashing fifty yards into the open on one occasion to rescue a wounded Marine lying helpless beyond the front lines.

Fighting fiercely in hand-to-hand encounters, he led his men in furiously waged battle for approximately ten hours, tenaciously holding his line and repelling the fanatically renewed counterthrusts until he succeeded in crushing the last efforts of the hard-pressed Japanese early the following morning.

His inspiring conduct throughout the critical periods of this decisive action enhanced and sustained the highest traditions of the United States Naval Service.
