On December 10th the new battleships _Benbow_ and _Emperor of India_ arrived from Berehaven to strengthen the 4th Battle Squadron, and proved very welcome additions to the Fleet. They, as well as all other new ships joining, necessarily spent several weeks in practices before becoming efficient to join the Fleet at sea, or to take part in action. Owing to the hurried completion of these two ships, a great deal of fitting work was also required before they were in a proper condition, and this delayed their practices considerably. On the 11th another gale was experienced which lasted until the 14th. The weather during this period was very bad, and ships at sea (including the 1st Battle Squadron which returned to Scapa on the 12th) met with very bad weather. Destroyers on patrol were unable to maintain their stations and were forced to run for shelter, and one of them, the _Cockatrice_, suffered some damage. On the 12th the work of retubing the port condenser of the _King George V._ was completed; the starboard condenser was not taken in hand owing to the small margin of superiority of the Battle Fleet over the High Sea Fleet at this time. During this stay of the Battle Fleet some very necessary work in the ships of the “Iron Duke” class was partially carried out. These ships were the first modern battleships fitted with 6-inch guns for their secondary armament, and the gunports were very low. Early in the War it was found necessary to unship the ports altogether, as the sea washed them away constantly. Water then had free access to the inside of the ship through the opening between the revolving shield and the ship’s side, and, except in fine weather, water entered freely. In bad weather the water, as deep as three to four inches, was continually washing about the living decks and finding its way below through the open hatches, to the great discomfort of the ship’s company, who were continually wet, and to the detriment of efficiency. Arrangements were devised on board the _Iron Duke_ to overcome this trouble, and steps taken to have all the necessary fittings made at various contractors’ yards. A partial bulkhead was fitted in rear of the guns to confine the water which entered the ship, and watertight indiarubber joints provided between the gun shields and the ship’s side. The result was satisfactory, and similar changes were made in the ships of the “Queen Elizabeth” class and in the _Tiger_. The two after 6-inch guns, which were on the main deck level, were removed altogether at the first opportunity, and the ship’s side and armour completed in the after embrasure in all these ships, as it was apparent that these guns could never be worked at sea, being only a few feet above the water line. The guns themselves were mounted in new unarmoured casemates on the superstructure deck level. The work connected with the forward 6-inch guns was entirely carried out at Scapa, with the ships at short notice
