they didnt march into the fire at the Somme like they did at Gettysburg. There wasn't any marching as such and it wasn't the Napoleonic school at the time....
at the Battle of the Somme, they used an early and horribly thought out version of the loose order drill that was used very successfully in World War 2.
I was referring to the whole notion of massed charge against fortified positions. The lack of imagination was appalling.
