I was reading up on the Battle of the Atlantic and came across a transcript of a letter home, written by the Navigating Officer of HMCS St Laurent. He said that their captain was far too old to be in command of a warship at sea: he slept on the bridge and was always worn out and fatigued.
Their captain was an RCN Commander aged just 32 at the time; he was not only captain of St Laurent, but also commander of long range escort group C1, directly in command of six warships and over 800 officers and men. Not to mention responsibility for the safety of his convoys - usually around 80 ships and another 1500 merchant navy sailors.
The navigating officer in question was 22 years old. Stupid Boy!
