 This is where the free world ends, and the communist dominion begins. This is the border between West Germany and Eastern Europe. Here is where Winston Churchill's simile of the iron curtain is made terrifyingly real. Hundreds of miles of high steel fence along the boundaries of East Germany and Czechoslovakia. It is from somewhere behind this steel barrier that attack would come should the communists employ armed force to press their dream of world domination. So it is that men of the United States Army patrolled the roads along the fence on watch day and night. Keeping their vigil in the air as well as on the ground. Reports flow back constantly to two United States cavalry regiments that are poised along the border of West Germany. Ready to hurl themselves at the foe should invasion come. Determined to slow his advance until the free world deploys its armed might. For this is the frontier of freedom. These men are the border watchers.
