She was refitted between 25 April and 12 May to have four worn-out 12-inch guns replaced and the secondary armament reduced and given casemates. Rear-Admiral Horace Hood took command of the 3rd BCS on 27 May 1915 and hoisted his flag in "Invincible". The 1st and 3rd BCS had sortied in response to the German bombardment of Yarmouth and Lowestoft on 24–25 April 1916, but failed to locate the German ships in heavy weather. During the return home, "Invincible" was rammed by the patrol yacht "Goissa" at 23:07. "Goissa"s bow was embedded in "Invincible"s side which partially stove-in. "Invincible"s speed was reduced to through flooding and she was forced to haul out of line and proceed independently to Rosyth for repairs which lasted until 22 May 1916. At the end of May 1916, the 3rd Battlecruiser Squadron was temporarily assigned to the Grand Fleet for gunnery practice. On 30 May, the entire Grand Fleet, along with Admiral Beatty's battlecruisers, had been ordered to sea to prepare for an excursion by the German High Seas Fleet. In order to support Beatty, Admiral Hood took his three battlecruisers ahead of the Grand Fleet. At about 14:30, "Invincible" intercepted a radio message from the British light cruiser , attached to Beatty's Battlecruiser Force, reporting the sighting of two enemy cruisers. This was amplified by other reports of seven enemy ships steering north. Hood interpreted this as an attempt to escape through the Skagerrak and ordered an increase in speed to at 15:11 and steered East-Southeast to cut off the fleeing ships. Twenty minutes later, "Invincible" intercepted a message from Beatty reporting five enemy battlecruisers in sight and later signals reporting that he was engaging the enemy on a south-easterly course. At 16:06, Hood ordered full speed and a course of south-southeast in an attempt to converge on Beatty. At 16:56, with no British ships in sight, Hood requested Beatty's course, position and speed, but never received a reply. Hood continued on course until 17:40, when gunfire was spotted in the direction to which his light cruiser had been dispatched to investigate other gunfire flashes. "Chester" encountered four light cruisers of Hipper's 2nd Scouting Group and was badly damaged before Hood turned to investigate and was able to drive the German cruisers away from "Chester".
