Do you recognize this story ?

[ponteranica.livejournal.com]

Hello to all!
I’m trying to find a story (that I was sure to have saved on my kindle but now is disappeared)
The boys are on manouvres in the country
There are some others two or three groups, and there is a bet between Cowley and another commander
I remember the Boys camping under some apple trees; another group having an injury and them giving help

Ring a bell?

Thank you so much for any help, is driving me crazy trying to remember the title !
