The item under Canada about the mutiny on the HMCS Iroquois was interesting. “Mutiny onboard destroyer HMCS Iroquois against commanding officer Cdr William Boyd Love Holms RCN. ..... The junior rates locked themselves on their messdecks while Holms fell down to knock himself unconscious in his bathroom. The mutiny ended when Holms was stretchered ashore.”
It makes one wonder how much help the Caption had in ‘knocking himself unconscious’.
