In January 1692*, the Inniskillings were stationed in the Tower of London. While they were there, an upper storeroom floor in the White Tower collapsed under the weight of thousands of barrels of gunpowder. The duty of clearing away this dangerous mess fell to the lot of the Inniskillings, yet so well was it done that not only were there no accidents but not even a rumour of what might easily have been a catastrophe reached the outside world.

*The exact date of this event is not known although it is known to have occurred in January 1692.
