depots. Many photographs of Confederate soldiers from later in the war (usually casualties) are wearing standardised uniforms. As Sherman's men marched across Georgia and up the Carolinas, they were cut off from supply by the Union and began wearing clothing of Confederate origin. Confederate soldiers used a variety of vegetable and imported dyes which would fade to a "butternut" colour. End of bright colours Until 1914 the majority of armies still provided colourful dress uniforms for all ranks, at least for parade and off-duty wear. These often retained distinctive features from the past. Most Russian troops, for example, wore the very dark green introduced by Peter the Great in 1700. German infantry generally wore the dark "Prussian blue" of the previous two centuries. This and other features of the historic Prussian Army uniform were generally adopted by the other German States as they fell under Prussian influence before and after the Franco-Prussian War of 1870. Bavarians, however, continued to wear light blue and Saxon regiments retained a number of distinctions after the establishment of the German Empire (1871). Two regiments of the Prussian Guard and one of the Russian were still issued with the brass mitre caps of the 18th-century grenadier. The British infantry retained their scarlet tunics for parade and "walking out" wear, while the bulk of French regiments wore red trousers with dark or light blue tunics. The infantry of the Austro-Hungarian Empire discarded their historic white tunics in 1868 in favour of dark blue. However, the extremely large number of colours appearing on collars, cuffs, and shoulder straps to distinguish the various regiments were retained. There were for example ten shades of red, ranging from cherry red to pink. The Swedish Army had favoured dark blue with yellow facings since the beginning of the 18th century. There was infinite variety, even within smaller armies, between regiments, branches or ranks and the subject is a complex one. The British were the first to introduce drab/khaki uniforms: in 1848 in India. This khaki drill then became more generally worn from the Indian Rebellion of 1857 both in India and Africa. A darker version, known as "service drab", was adopted for home service field wear in 1902, the same year that the US Army also adopted khaki for non-dress occasions. The Italians introduced grey-green in 1909, followed by the German and Austrian armies who adopted different shades of grey. The
