remembered that a soldier had to march, parade, fight and sometimes sleep in the same garment and that such extras as greatcoats or working clothes were seldom issued until the end of the century. Ottoman Empire The highly organised armies of the Ottoman Empire employed distinctive features of dress to distinguish one corps or class of soldier from another. An example would be the conical black hats of felt worn by the Deli cavalry of the early 19th century. However the basic costume was usually that of the tribal group or social class from which a particular class of warrior was drawn. As such it was sufficiently varied not to rank as "uniform" in the later sense. An elaborate system of colourful standards largely provided unit identification. Even the appearance of the Janissaries was likely to reflect individual means and taste, although red was a favoured colour and the white felt zarcola headdresses were similar. It was not until the reorganisation of the Ottoman Army by Sultan Mahmud II during the 1820s that completely standardised dress was issued. Later modern era The first fifteen years of the 19th century influenced the appearance of military uniforms until the 1850s. In particular, some uniforms of the Grande Armée – notably those of the cavalry regiments of the Imperial Guard – are considered as being amongst the most striking and distinctive of the time. The cost of the French uniforms varied widely, going from 200 to 250 francs for a line infantryman's outfit to 2000 francs for a cuirassier's uniform. Cavalrymen of the Guard had no fewer than 10 different uniforms. One justification for the expensive parade dresses of the Guard was that they would "lead the people of the conquered nations to regard the French uniforms with unreserved astonishment". As a general trend France and other European states replaced their bicornes by feathered shakos or crested helmets, while the coatee-type jacket replaced the combination of tailcoat and waistcoat. The ornamental peak of the military uniform was reached in the early 19th century in Western Europe. Sometimes the Napoleonic Wars are identified as being the acme of colourful and ornate uniforms, but actually the several decades of relative peace that followed were a time of even more decorative styles and embellishments. The Napoleonic soldier on campaign was likely to present a shabby and nondescript appearance as unsuitable peacetime dress quickly deteriorated or was
