15. Base your answer on the poem below and on your knowledge of social 3 studies. AttackAt dawn the ridge emerges massed and dun [brownish dark
grey]In the wild purple of the glowering (glaring] sun, Smouldering through
spouts of drifting smoke that shroudThe menacing scarred slope; and,
one by one, Tanks creep and topple forward to the wire. The barrage roars
and lifts. Then, clumsily bowedWith bombs and guns and shovels and
battle-gear, Men jostle and climb to meet the bristling fire. Lines of grey,
muttering faces, masked with fear, They leave their trenches, going over
the top, While time ticks blank and busy on their wrists, And hope, with
furtive eyes and grappling fists, Flounders in mud. O Jesu, make it
stop!Source: Siegfried Sassoon, 1918Which claim about modern warfare is
