Second Sikh War
A fracas at Ramnagar was followed by a right old kicking at Chillianwala, where the 24th Foot got virtually annihilated (and a repeat performance thirty years later). Despite odds of 30-40,000 Sikhs against 12,000 of General Gough's men, the old bugger still managed to pull off a victory - albeit with appalling losses.
The final punch up was at Goojerat, with 60,000 Sikhs & Afghans versus Gough's 24,000 reinforced army. Needless to say, Johnny Foreigner got a total pasting, the Sikhs joined the British Indian Army, and it was all Pimms & Cricket henceforth. The Afghans, however, remained a pain in the arrse - and still are to this very day!
