英语翻译Never in the field of human conflict was so much owed by

倒装,正常顺序：
so much was never owed by so many to so few in the field of human conflict
so much,这里是不可数的代词
翻译：
从没有在哪个人类冲突的场地（就是战场的意思）,那么多人对那么少的人欠下那么多的债务.

So much was never owned by so many to so few in the field of human conflict.

楼上说的都蛮好的，我补充下，这句话的出处是Winston Churchill,用来称赞英伦之战中保卫英国领空抵御纳粹空军的战斗机飞行员的！
