The well-trained and disciplined Prussian horse during the Hundred Days campaign formed regiments of cuirassiers, dragoons, hussars and lancers on the whole with the lighter cavalry intended for raiding and skirmishing, but in reality took their place in the main battle lines during set piece battles.
The Uhlans, or lancers, of the Prussian army fulfilled the role of both skirmishing light cavalry and line shock troops alongside the dragoon and cuirassier units. Equipped with a lethal 9-foot lance, they were an imposing sight. It was the Uhlans who saved Marshall Blu?cher when unhorsed at Ligny.
Late war Uhlans principally wore simple dark blue uniforms and practical equipment. By the Battle of Waterloo in 1815, all units had their lance pennants with black and white swallow tail pattern.
