Concentrating on quick barrages and shock troops. But too late.
Overall, it was the dumbest war in human history. They’re all dumb, to some degree...but there was no reason for WWI, and it was fought remarkably stupidly.
A good mini-stat, which exemplifies this asinine war: there was one final assault on the morning of 11/11/18, when everyone knew the war would be over at 11 am. The whistles blew (literally) at 11...but not before 10,000 new, utterly pointless casualties had been added to the millions of utterly pointless ones that had gone before.
