"an implacable enemy"

Used in print

(Howard Fast, April Morning....)

One moment , the road was filled with disciplined troops , marching four by four with a purpose as implacable as death ; the next , a cloud of gun_smoke covered a screaming fury of sound , out of which the redcoat soldiers emerged with their bayonets and their cursing fury .
