Just dug a little deeper:

H. 10 sighted the Commodore’s force. The range luckily was such that the ships were beyond attack and, moreover, she recognised them as apparently British. Otherwise she had nothing to report. E16 observed Zeppelins and torpedo boats but all beyond range, till on December 22 she discovered a large vessel strongly escorted. Thinking this must be of some value, Lieutenant-Commander Duff-Dunbar, commanding E16, decided to attack and fired a torpedo. It missed. E16 had been sighted by one of the screening vessels only 50 yards ahead of her. Although it turned to ram her, Lieutenant-Commander Duff-Dunbar fired a second torpedo at the large ship and had the satisfaction of seeing it hit before he dived to escape being rammed. In the course of'the hunt for E16 which followed, the high speed of the hunting craft frustrated any chance of attack on them.
