John FitzAlan, 1st Baron Arundel

Commanding a force with the purpose of bringing relief to the Duke of Brittany, Sir John was compelled to wait for stronger winds.

During this wait he decided to take refuge in a nunnery, where his men "took no notice of the sanctity of the place and... violently assaulted and raped"[1] those they found inside.

[1] When the force eventually set out to sea, carrying with them goods stolen from a nearby church and under a pronouncement of excommunication from the wronged priests, the expedition was caught in a storm.

Thomas Walsingham reports that during the panic of the storm, Sir John murdered those of his men who refused to make for shore for fear of being shipwrecked upon the rocks.

Subsequently, after safely arriving on an island off the Irish coast, Sir John and his boat captain were swept back into the sea and drowned.
