The dead of the war stand in gloom
A scarlet tinge for the muted room
People beaten by tools of war
Stand together, forgotten in law
My conscience took my by the hand
Or cowardice I turned and ran
Murdered by our former friends
Comrade's lives now loose ends
Anxiety and anger purge my heart
This beats to the soldier’s steady march
Into battle we must go
Our general shouted, we moaned and groaned
A shell amiss, an ‘honourable death’
The recollection of quickened breaths
The flicker book of Sundays passed
A life that was meant to last
Respect upmost those who fought
Let them occupy your thoughts
I’m not the mean and selfish kind
These people will always fill my mind
I loved my life, I treasured it
Now memories come back in bits
We marched in battle, four by four
We are the dead of the war
Poem depicts the loss of war in a very effective manner. However I too agree that there is a scope of improvement.
This convey the sense of the loss of war effectively. There are some good images - such as the first line.
If you're writing rhyming verse, it's good to look for enjambment - ie carrying the sense of the sentence beyond the line- end rhyme. This lessens the danger of sounding too sing-song.
Also, check your scansion. Although the poem is mainly in iambic meter, there are some lines which don't fit this pattern. Read your work out loud and see what jars.
