"Martinez was a Mexican-American born to Mr. and Mrs. Francisco Martinez in Fort Hancock, Texas. There, he received his primary and secondary education. He joined the United
States Army in 1950 at the recruiting station in his hometown. Martinez completed his basic training and was eventually assigned to Company A (Able Company) of the 27th
Infantry Regiment.
Korean War
The North Korean Communist forces invaded the Republic of Korea on June 25, 1950. The 27th Regiment, 25th Infantry Division (whose nickname was "Wolfhounds") was stationed in Hawaii and in July was put on alert. By July 18, the entire division was in Pusan in Republic of Korea.
On February 23, 1952, the 25th Division, under the command of Major General Ira P. Swift, was in the front line in the center of the X Corps sector near Mundung-ni northeast of the Hwach'on Reservoir. The division assumed the front line routine of patrols, ambushes, artillery exchanges, and bunker maintenance. The division also secured and defended forward outposts beyond the main line of resistance.
Martinez's unit, the 2nd Platoon of A Company, inherited a position known as Sandbag Castle from Charlie Company (C Company). On the night of September 5, 1952, Corporal Martinez was in Outpost Agnes performing forward listening post duties. Outpost Agnes was a bunker large enough to hold four soldiers. Shortly after midnight, the North Koreans began shelling Sandbag Castle. During a lull in the shelling, the men of the 27th inside the castle were able to spot crawling North Korean soldiers whose intentions were to cut off the forward bunkers and Outpost Agnes.
Martinez ordered the three men in his bunker to return to the Sandbag Castle. His commanding officer, Lieutenant McLean called him on the sound power telephone and ordered him to get out. Martinez, knowing the situation better than anyone, replied that he would have to stay on and delay the North Koreans as long as possible. Martinez remained at his post and with his machinegun inflicted numerous casualties on the attacking troops. When he ran out of ammunition he retreated to a bunker destroyed by enemy shelling and from there continued his assault with a Browning Automatic Rifle (BAR). Martinez was mortally wounded before his unit was able to counterattack and regain their terrain.
On December 29, 1953, President Harry S. Truman presented the family of Benito Martinez with the Medal of Honor."

Citation: Cpl. Martinez, a machine gunner with Company A, distinguished himself by conspicuous gallantry and outstanding courage above and beyond the call of duty in action against the enemy. While manning a listening post forward of the main line of resistance, his position was attacked by a hostile force of reinforced company strength. In the bitter fighting which ensued, the enemy infiltrated the defense perimeter and, realizing that encirclement was imminent, Cpl. Martinez elected to remain at his post in an attempt to stem the onslaught. In a daring defense, he raked the attacking troops with crippling fire, inflicting numerous casualties. Although contacted by sound power phone several times, he insisted that no attempt be made to rescue him because of the danger involved. Soon thereafter, the hostile forces rushed the emplacement, forcing him to make a limited withdrawal with only an automatic rifle and pistol to defend himself. After a courageous 6-hour stand and shortly before dawn, he called in for the last time, stating that the enemy was converging on his position His magnificent stand enabled friendly elements to reorganize, attack, and regain the key terrain. Cpl. Martinez' incredible valor and supreme sacrifice reflect lasting glory upon himself and are in keeping with the honored traditions of the military service.
