distant musket fire. The horse was afforded protection from lances and infantry weapons by steel plate barding. This gave the horse protection and enhanced the visual impression of a mounted knight. Late in the era, elaborate barding was used in parade armour. Later Gradually, starting in the mid-16th century, one plate element after another was discarded to save weight for foot soldiers. Back and breast plates continued to be used throughout the entire period of the 18th century and through Napoleonic times, in many European (heavy) cavalry units, until the early 20th century. From their introduction, muskets could pierce plate armour, so cavalry had to be far more mindful of the fire. In Japan armour continued to be used until the end of the samurai era, with the last major fighting in which armour was used happening in 1868. Samurai armour had one last short lived use in 1877 during the Satsuma Rebellion. Though the age of the knight was over, armour continued to be used in many capacities. Soldiers in the American Civil War bought iron and steel vests from peddlers (both sides had considered but rejected body armour for standard issue). The effectiveness of the vests varied widely—some successfully deflected bullets and saved lives, but others were poorly made and resulted in tragedy for the soldiers. In any case the vests were abandoned by many soldiers due to their weight on long marches as well as the stigma they got for being cowards from their fellow troops. At the start of World War I, thousands of the French Cuirassiers rode out to engage the German Cavalry. By that period, the shiny armour plate was covered in dark paint and a canvas wrap covered their elaborate Napoleonic style helmets. Their armour was only meant for protection against edged weapons such as bayonets, sabres, and lances. Cavalry had to be wary of repeating rifles, machine guns, and artillery, unlike the foot soldiers, who at least had a trench to give them some protection. Present Today, ballistic vests, also known as flak jackets, made of ballistic cloth (e.g. kevlar, dyneema, twaron, spectra etc.) and ceramic or metal plates are common among police forces, security staff, corrections officers and some branches of the military. The US Army has adopted Interceptor body armour, which uses Enhanced Small Arms Protective Inserts (ESAPIs) in the chest, sides, and back of the armour. Each plate is
