Summary

W. J. Loftie Authorised Guide to the Tower of London

On Henry VIII's death the first inventory of the Royal collection was made, and this includes the armour and arms at Greenwich, and arms and artillery at the Tower of London which, from the time of Henry VIII, was one of the sights for foreigners of distinction. In the troubles of the Civil War the arms were drawn out, and there is no doubt much, both of arms and armour, was used and lost. The Protector took one suit, and it was not till 1660 that the armour, which had meanwhile been brought to London, was collected, and, with the weapons still in the store, were formed into a kind of museum.

What actually did cause the disuse of armour was the change in ideas as to the movement of troops and the large quantity of armour which was made in the sixteenth century, and consequently the inferior make. In England the disuse of armour seems to have begun earlier than on the Continent, but at no time were the ordinary soldiers covered with metal as seen in Armouries and other places. The weight, and what was more important, the cost, prevented such a thing. It was only the rich who could afford to pay for and had horses to carry armour, who wore much of what we see now.

Again, armour for war was much lighter and less complete than that used for the tilt yard, where protection to the wearer was more considered than his ability to hurt his opponent. The greater substance of such armour and its frequent enrichment with engraving and gilding no doubt led to the preservation of this class of defence. Chain mail suffered extremely by rust and neglect, and even plate armour was subject to the same deterioration. It is consequently not to be wondered at that little or no armour of a date previous to the fifteenth century is to be seen in this collection.
