Great battle report! I'm sure her majesty's men would have won out. Barely, maybe, but won!
We played a Rorke's Drift(ish) scenario this August past using Fistful of Lead: Bigger Battles. British marksmanship vs. Zulu "up close and personal", it was. The Brits squeaked out wins both time we played it, but it they were both near-run things...
