Rupert Brooke (1887-1915) wrote in the neo-Romanticism style of the Georgian Poets. Although often regarded as a war poet, enthusiasts regard him as truely a pre-war poet.
Brooke's entire reputation as a war poet rests on only 5 "war sonnets" (6 if you count "Treasure" -- unnumbered in his short sonnet cycle). Brooke's war experience consisted of one day of limited military action with the Hood Battalion during the evacuation of Antwerp.

He was born one winter morn
With hands delicious,
And it was well with us.
Love came our quiet way,
Lit pride in us, and died in us,
All in a winter
