Of the 221 U.S. Marines captured during the Korean War, more than half—121—were seized after 20 September 1951. For the Marine Corps this date marked the time when “warfare of position replaced a warfare of movement throughout the remaining 22 months of the conflict in Korea.”[565] Both in the X Corps sector in eastern Korea where the 1st Marine Division was located at that time, as well as later on the Korean western front, the Marine Corps was denied its traditional aggressive fighting role. The Marines (along with the rest of the UNC forces) ceased offensive operations, were reduced to making limited attacks, and were under order from higher echelons to “firm up the existing line and to patrol vigorously forward of it.”[566]

The mission of the Marine division thereby evolved into “an aggressive defense of their sector of responsibility” as records duly phrased it. On a larger scale, the nature of the Korean War, from about November 1951 on, reverted to that of July and August,[567] characterized primarily by minor patrol clashes and small unit struggles for key outpost positions. This became the pattern for the remainder of the war. It changed only when the decreed mission of an “active defense of its sector” by a UNC unit became this in fact. Normal defense then escalated into sharp, vigorous fighting to retain friendly key ground positions being attacked by the enemy. One American writer, in a discussion of the British defense in depth concept (adopted by the Marine Corps late in the war), went so far as to blame heavy Marine casualties in Korea on EUSAK’s outpost system.[568]

[567] In July 1951, fighting had quieted down all along the UNC front, as a result of truce talks initiated by the Communists. This conveniently provided the enemy, at that time hard-pressed, a much-needed breathing spell. The lull in ground fighting continued until late August when the truce negotiations were suspended.

Approximately half of the 100 Marines taken prisoner by September 1951—43—had fallen into enemy hands during the last two days of November 1950. They had been part of the ill-fated Task Force Drysdale,[569] a composite Royal Marine-USMC-Army convoy that was ambushed by the Chinese en route to the Chosin Reservoir. These facts are relevant to a better understanding of the Commandant’s statement that, traditionally, few Marines become prisoners of war.

Overall, the survival rate for Marines taken captive during the Korean War was 87.8 percent. Even for the worst year, 1950, when NKPA treatment was more ruthless and brutal than the CCF (and in any event, for those men longest-held), the Marine survival rate was 75 percent. Marine Corps statistics show that of 221 Marines captured, 194 (43 officers, 151 enlisted) returned, and 27 or 12.2 percent died.[570] Only a few Marines were afflicted with “give-up-itis,” the malady that struck countless POWs and took a heavy toll of lives. Included among these 194 returnees were the 172 men from the two POW exchanges, as previously noted; plus a group of 18 Marines captured in 1950 who escaped and rejoined USMC units in May 1951; two enlisted men who escaped less than a week after being taken; and two others released by the enemy after less than a month’s captivity.

[570] Records indicate that 3 officers and 18 enlisted died while in captivity. Three officers and 3 enlisted POWs were also presumed to have died. MacDonald, POW, pp. 257–259.
