Which TWO parts highlight the psychological consequences of war? 1. But now I've said goodbye to Galahad,
And am no more a knight of dreams and show:
For lust and senseless hatred make me glad,
And my killed friends are with me where I go
Wound for red wound I burn to smite their wrongs;
And there is absolution in my songs.
(Siegfried Sassoon, "Poet as Hero")

1. Men marched asleep. Many had lost their boots
But limped on, blood-shod. All went lame; all blind;
Drunk with fatigue; deaf even to the hoots
Of tired, outstripped Five-Nines that dropped behind.
Gas! Gas! Quick, boys!–An ecstasy of fumbling,
(Wilfred Owen, "Dulce Et Decorum Est")
