The Crimean War was the first major European war since the end of the Napoleonic Wars and Britain's only war on that continent in the century between Waterloo and WW1\. When Russia invaded provinces of the Ottoman Empire, the British and French, later joined by the Kingdom of Piedmont-Sardinia, intervened to limit Russian expansion towards the Black Sea.Each of the armies contained an eclectic mix of units. The regular European regiments still displayed much of the bright colour and finery associated with the Napoleonic era (the British infantry in their scarlet tunics forming the famous thin red line' at Balaklava for instance), while each also contained a mix of exotic units drawn from across their respective empires. The French fielded Zouaves and Spahis from North and West Africa, not to mention the legendary Foreign Legion; the Ottomans had Tunisians and Egyptians alongside Balkan mountaineers and the infamous Bashi-bazouks; the Russians of course had their Cossacks and the British fielded little-known German, Swiss and Italian mercenaries. Gabriele Esposito details the composition, organization, uniforms and weaponry of each force and illustrates many of them with early black and white photos (this being the first major war for which photography was available), as well as numerous colour artworks.
