The two new battleships, the _Emperor of India_ and _Benbow_, the former flying the flag of Rear-Admiral A. L. Duff, C.B., had arrived at Berehaven in the south of Ireland on December 1st to “work up” after commissioning. On the same date the _Leviathan_ arrived at Cromarty to act as flagship of the 1st Cruiser Squadron under the orders of Rear-Admiral Sir A. G. W. Moore. His flag was transferred to her from the _New Zealand_ on December 2nd. On the night of December 2nd a very violent gale sprang up at Scapa Flow, during which several ships dragged their anchors, in spite of two anchors being down and steam up; the gale lasted until the morning of the 4th. All communication between ships in Scapa Flow, even by drifter, was suspended, and the light cruisers at sea on patrol were forced to lie to. An officer and one man were washed overboard from a picket-boat sheltering under the stern of a store-ship and drowned. On December 3rd Rear-Admiral Dudley de Chair, lately in command of the 10th Cruiser Squadron, hoisted his flag in the armed merchant ship _Alsatian_ to command the merchant cruisers attached to the Grand Fleet, which were now constituted as the new 10th Cruiser Squadron. At 1.45 P.M. on December 3rd the destroyer _Garry_, Commander W. W. Wilson, of the local defence force, reported that she was engaging a submarine at the Holm Sound entrance to Scapa Flow. This submarine was possibly sheltering there from the bad weather. Destroyers and trawlers were at once sent out to assist, and the submarine was last reported diving to seaward. Several rounds from her 12-pounder gun were fired by the _Garry_ at the submarine’s conning tower, but apparently without effect, and an attempt to ram her also failed owing to the heavy sea and very strong tides. The submarine and the _Garry_ fired torpedoes at one another, the submarine’s torpedo passing under the stern of the _Garry_. All ships were directed to raise steam for leaving harbour on receipt of the first report from the Garry, from which it was not clear whether the submarine had passed through Holm Sound into the harbour, but this order was cancelled when it was ascertained that she was outside.
