Before the brig, men who needed locking up were held in the lamproom.It was the second most secure place apart from weapons and they were not going to lock them up there. It is said that Captain Peter Sally on his last voyage ran short of rations and served up the remains of a dead horse that had been smuggled on board to order. The meat was stacked in the lamproom along with the prisoners. Overcome by the fumes of rotting meat they tried to get out but were ignored, despite their cries for help. Seven months later the remains of animal and men were found ,with the nails of the men embedded in the back of the lamproom door.They stayed there on view at Portsmouth till Frances Grant a collector of oddities, purchased the dead door nails for the sum of two pounds. At auction in 1972 they were sold for nine hundred pounds by a buyer who claimed to already have some of Robin Hoods' un-used arrows, and a spy-glass that belonged to Nelson. Hope that's of some help.
