I've always been fascinated by the Crimean War: one of the last few classically 'Napoleonic' wars before technology changed things again.
My Crimean Russians are a nice little army: solid battalions of drab-coated infantry commanded by glittering officers, supported by equally solid masses of cavalry and hordes of Cossacks. Although most of the army is painted to the standard I was achieving at the time, the officers and Dragoon Guards show that I was reaching for more.
The figures are mostly Essex, IIRC, with quite a few Minifigs thrown in, and one unit from Irregular. Confession time: the Hussars were bought painted at a Bring and Buy, and the Don Cossacks were painted by the Irregular Miniatures painting service. All the rest are my work...and I do love the Dragoon Guards!
