widely employed to train and organize national armies. Peru was the first to use the helmet for the Peruvian Army when some helmets were shipped to the country in the 1870s, but during the War of the Pacific the 6th Infantry Regiment "Chacabuco" of the Chilean Army became the first Chilean military unit to use them when its personnel used the helmets—which were seized from the Peruvians—in their red French-inspired uniforms. These sported the Imperial German eagles but in the 1900s the eagles were replaced by the national emblems of the countries that used them. The Russian version initially had a horsehair plume fitted to the end of the spike, but this was later discarded in some units. The Russian spike was topped with a grenade motif. At the beginning of the Crimean War, such helmets were common among infantry and grenadiers, but soon fell out of place in favour of the forage cap. After 1862 the spiked helmet ceased to be generally worn by the Russian Army, although it was retained until 1914 by the Cuirassier regiments of the Imperial Guard and the Gendarmerie. The Russians prolonged the history of the pointed military headgear with their own cloth Budenovka adopted in 1919 by the Red Army. Derivatives In 1847, the Household Cavalry, along with British dragoons and dragoon guards, adopted a helmet which was a hybrid between the Pickelhaube and the traditional dragoon helmet which it replaced. This "Albert Pattern" helmet was named after Albert, Prince Consort who took a keen interest in military uniforms, and featured a falling horsehair plume which could be removed when on campaign. It was adopted by other heavy cavalry regiments across the British Empire and remains in ceremonial use. The Pickelhaube also influenced the design of the British army Home Service helmet, as well as the custodian helmet still worn by police in England and Wales. The linkage between Pickelhaube and Home Service helmet was however not a direct one, since the British headdress was higher, had only a small spike and was made of stiffened cloth over a cork framework, instead of leather. Both the United States Army and Marine Corps wore helmets of the British pattern for full dress between 1881 and 1902. Design The basic Pickelhaube was made of hardened (boiled) leather, given a glossy-black finish, and reinforced with metal trim (usually plated with gold or silver for officers) that
