On 4 July 1915 in the Atlantic, south-west of Queenstown, Ireland, HM Horse Transport Anglo-Californian, commanded by Captain Parslow, was attacked with gunfire by a submarine which made occasional hits although the Captain kept altering course. At last, on the point of abandoning ship in order to save lives, a message was received to hold on as long as possible and Anglo-Californian got under way again, whereupon the U-boat opened a very heavy fire, doing great damage. Captain Parslow remained on the bridge throughout the attack, entirely without protection and was killed when the bridge was wrecked.
