and here is a funny event that occured during those days that the Marines were trapped and waiting for the Treadway bridge.
"Air support for the entire series of operations would remain critical; without it the men on the ground would be on their own, vastly outnumbered in a bad tactical situation. The 1st Marine Air Wing endeavored to keep 24 attack aircraft over the withdrawing column at all times during daylight in order to provide immediately available fire support. At night, specially equipped fighter aircraft could offer some degree of coverage.
In addition to the Marine Air Wing, Navy aircraft flying from carriers in the Sea of Japan and Air Force planes from other parts of Korea tried both to keep the troops on the ground supplied and the Chinese under constant pressure. But the weather often did not cooperate, and the Air Force was simultaneously engaged in massive support of the Eighth Army’s crumbling front in western Korea.
Because of these airmen, the troops on the ground retreating from Chosin Reservoir were well supplied with ammunition. Food was a different matter, however. The C-rations and K-rations carried by the troops were frozen solid and could not be readily thawed. Lighting fires along the route of march presented the obvious problem of drawing enemy fire, especially at night. As the breakout progressed from Yudam-ni to Hagaru-ri to Koto-ri, the men were continually drained of energy. In a moment of complete comic relief, at Koto an airdrop delivered boxes of condoms to the Marines, who quipped, “What do they think we are doing with those Chinese, anyway?”........
