_1st Battle Squadron_: 7 ships (_Superb_ was away). _2nd Battle Squadron_: 6 ships (_Conqueror_ was unserviceable). _4th Battle Squadron_: 7 ships (complete). _3rd Battle Squadron_: 6 ships (_Commonwealth_ and _Britannia_, refitting). _1st Battle Cruiser Squadron_: 2 ships (_Lion_ was effecting temporary repairs; the _Tiger_ refitting). _2nd Battle Cruiser Squadron_: 1 ship (_Indomitable_ refitting after a fire, due to defective electric circuits). _1st Cruiser Squadron_: 4 ships (complete). _2nd Cruiser Squadron_: 3 ships (_Natal_ refitting). _3rd Cruiser Squadron_: 3 ships (_Roxburgh_ refitting). _6th Cruiser Squadron_: 3 ships (complete). _7th Cruiser Squadron_: 3 ships (complete). _1st Light Cruiser Squadron_: 4 ships (complete). _2nd Light Cruiser Squadron_: 4 ships (_Liverpool_ refitting). _2nd Flotilla_: 11 destroyers (5 refitting, 4 detached in the Irish Sea). _4th Flotilla_: 11 destroyers (5 refitting, 4 detached in the Irish Sea). The shortage of destroyers at this period was exceedingly marked. During February the Battle Fleet remained in harbour. No enemy movements took place or were expected as several changes were being made in the High Sea Fleet commands; the principal of these was the relief of Admiral von Inghenol by Admiral von Pohl as Commander-in-Chief. It was anticipated that the new Flag officers would exercise their squadrons in order to become familiar with them before attempting any operations. The opportunity was taken of refitting the _Iron Duke_, and the ship remained at Invergordon, in the Cromarty Firth, until February 23rd. It was becoming desirable to give the officers and men of the Battle Fleet some change from Scapa Flow, where there were no opportunities for landing for exercise or recreation, and arrangements were made by which battle, as well as cruiser squadrons should visit Invergordon periodically for this purpose. The 2nd Battle Squadron accordingly arrived at this base on February 24th. During the first half of February, 1915, eight destroyers were absent from the Grand Fleet flotillas, working in the Irish Channel against submarines, leaving only a total of 20 to 22 available for the Fleet; an insufficient number for screening purposes. This deficiency made it desirable to keep the Battle Fleet in harbour, except in an emergency.
