Hi Olikara,
Welcome to the forum

. It is an interesting question you bring up, and Jim has, as always, done his homework well

.
It is true that the English collected lots of weapons and let them rust, till they could not be used for anything. Other weapons were used in the steel production, and when taking only these two ways of destruction, thousands of swords and daggers were destroyed. The British also destroyed about seventeen thousand of adya katars and other weapons after a riot at Coorg, but these weapons were taken out at sea, and thrown overboard. Although there were many different types of weapons, many thousands were destroyed, so to day, we only have ‘a few’ exambles.
