Strict requirements by I Corps enjoined that the “fence on the southern boundary of the DMZ must present a continuous unbroken line except for gates and where it crosses large streams.”[643] Beginning late on 27 July 1953, the 1st Marine Division’s modified mission became that of withdrawal to and organization of the post-armistice MBP, establishment of the No-Pass Line, and defense of the new position in readiness for any possible resumption of hostilities by the enemy.

Division officers, from commanding general to platoon leader level, repeatedly emphasized that the armistice agreement was only a cessation of active fighting. As such, it could be violated by the enemy at any time. The armistice was not a peace, but had simply paved the way for a political conference. As the UNC commander, General Mark W. Clark, had stated, the 27 July document was merely “a military agreement between opposing commanders to cease fire and to permit the opposing sides to arrive at a peaceful solution of the conflict.”[644] Since many felt the cease-fire might be only temporary and not necessarily a permanent peace, all hands showed an attitude of skepticism and watchful waiting. There was little disposition or time for celebration. The response of many men to the complete lack of noise across the front was one of simple restlessness and expectancy.

From the 7th Marines just engaged in the vicious Boulder City battle, the reaction

... was one of disbelief and caution. Extensive movements of the enemy during the night of 27 July only bolstered the feeling of wariness and suspicion. Only after dawn broke on 28 July, without any shots being fired, did the realism [reality] of the truce become apparent, followed by a wide-spread sensation of relief.[645]

A 5th Marines representative noted:

The fact that negotiations had been going on for some time with numerous false alarms dulled the edge for most people, and a prior announcement that the agreement would be signed took most of the steam away from the actual culmination of the fighting ... in effect [the cease-fire] meant “we’re giving you ten dollars but don’t spend it for we might take it back.”[646]
