As+under+a+green+sea,+I+saw+him+drowning.

This metaphor probably affected me most of all the metaphors in this poem, because, to an extent, I was able to relate to it. Obviously I cannot relate to drowning, but my family has a house upstate on a lake, and during the summer we swim there. I remember one time swimming with a few friends, and diving down about ten feet underwater. The water at the surface is pretty clear and harmless looking, but the water ten feet down was green, dark, and murky. As soon as I read this metaphor, I remembered that chilling vision, and how scary it was. The green sea clearly represents the green poisonous gas that killed this one soldier who wasn't quick enough to put on his gas mask. The man clearly didn't drown, but the gas-filled room might give the impression of being underwater, and his choking on the gas would give the impression of drowning.

Nicely done, Eddie. You show an understanding of the hazy, dangerous green and are able to smoothly relate it to your own life and experiences. Furthermore, your writing is well proofed, smoothly, and complete.
