After the arrival of the British Battle Fleet the enemy's tactics were of a nature generally to avoid further action, in which they were favored by the conditions of visibility. [Sidenote: Enemy entirely out of sight.] At 9 p.m. the enemy was entirely out of sight, and the threat of torpedo-boat-destroyer attacks during the rapidly approaching darkness made it necessary for me to dispose the fleet for the night, with a view to its safety from such attacks, whilst providing for a renewal of action at daylight. I accordingly man[oe]uvred to remain between the enemy and his bases, placing our flotillas in a position in which they would afford protection to the fleet from destroyer attack, and at the same time be favorably situated for attacking the enemy's heavy ships. During the night the British heavy ships were not attacked, but the Fourth, Eleventh, and Twelfth Flotillas, under Commodore Hawksley and Captains Charles J. Wintour and Anselan J. B. Stirling, delivered a series of very gallant and successful attacks on the enemy, causing him heavy losses. [Sidenote: Severe losses in the Fourth Flotilla.] It was during these attacks that severe losses in the Fourth Flotilla occurred, including that of _Tipperary_, with the gallant leader of the Flotilla, Captain Wintour. He had brought his flotilla to a high pitch of perfection, and although suffering severely from the fire of the enemy, a heavy toll of enemy vessels was taken, and many gallant actions were performed by the flotilla. Two torpedoes were seen to take effect on enemy vessels as the result of the attacks of the Fourth Flotilla, one being from _Spitfire_, and the other from either _Ardent_, _Ambuscade_, or _Garland_. [Sidenote: An enemy ship torpedoed.] The attack carried out by the Twelfth Flotilla was admirably executed. The squadron attacked, which consisted of six large vessels, besides light-cruisers, and comprised vessels of the _Kaiser_ class, was taken by surprise. A large number of torpedoes was fired, including some at the second and third ships in the line; those fired at the third ship took effect, and she was observed to blow up. A second attack, made twenty minutes later by _Maenad_ on the five vessels still remaining, resulted in the fourth ship in the line being also hit. The destroyers were under a heavy fire from the light-cruisers on reaching the rear of the line, but the _Onslaught_ was the only vessel which received any material injuries. In the _Onslaught_ Sub-Lieutenant Harry W. A. Kemmis, assisted by Midshipman Reginald G. Arnot, R.N.R., the only executive officers not disabled, brought the ship successfully out of action and reached her home port. During the attack carried out by the Eleventh Flotilla, _Castor_ leading the flotilla, engaged and sank an enemy torpedo-boat-destroyer at point-blank range.
