二战期间,英国蒙哥马利将军除了要在自己的前进方向作战外,还必须支援盟军作战,他和他的工程策划师们要承担起600万军事人员的军需、燃料、食品和所有其他的战争物资。在所有这些前线的背后,还需维持很长的供应线,要跨越广大的西德平原,要经过被破坏的公路、铁路隧道和桥梁来通过宽大的水面和高山的阻隔。 During World War II, General Montgomery of Britain, in addition to fighting in his own direction, must also support allied operations. He and his engineering planners must take over the military supplies, fuel, food, and all other war supplies of 6 million military personnel. . Behind all of these frontlines there is also the need to maintain a long supply line across the vast West Plains and through the vast water and mountains through the destroyed roads, railroad tunnels and bridges.
