Mace's tank, miraculously, had come through without loss among either crew or riders--the first and last vehicle to do so. Surprise, and their momentum, had served them well. And as they went through the British lines, these men knew the worst: that instead of holding only a small stretch of the road under light fire, a full Chinese division had locked itself over six miles of the route, covering it with small arms, mortars, and forty machine guns. Nor could Mace and party give warning; like those of the British, his radios wouldn't carry over the pass.
