For some great anti-war poetry, read Robert Service! You may have to get the complete works to find the war poetry as he is better known for his Yukon poems such as "The Ballad of Shark Tooth Shoal." It begins (from memory be kind) "The north country/ is a hard country/ that mothers a bloody brood/ But the wickedest known/ from Nome to the Pole/ was the Hermit of Shark Tooth Shoal."
Wonderful imagery. For example:
"He drained the morals clean as a soup tureen from the heart of that innocent child."
