I would agree with 90th.
This is a similar book: The story of Jabulani ka Sihayo.
" I ran and ran, screaming the worst curses I knew, hurtling completely alone into the enemy lines. There was thunder in my ears, but no lightning struck me down as I threw myself at the red soldiers, lashing out at their faces with my fists. they must have been amazed to see a Zulu boy suddenly dive into their shallow trenches, but in a minute they had swarmed over me and pinned me to the ground. For the next hour, while the battle raged around me, I lay struggling under the body of an English soldier as he handed up ammunition to his comrades."
Sounds brilliant but total fiction.
