"It was the mist," was the reply.  "The Huns got within thirty yards before we tumbled to it.  We did the best we could but they just swamped our position before we could get our cross-fire going.  Even at that we mowed them down in heaps with our rifle fire, but they kept on coming.  For every dead man there were twenty live ones to take his place.  We put up a stiff fight, but there were too many of them.  It seemed like millions.  They're coming now like a house afire and you boys want to brace."
