Ideally, the battle line would cross the intended path of the enemy column so that the maximum number of guns could be brought to bear, while the enemy could fire only with the forward guns of the leading ships, a manoeuvre known as "crossing the T". Admiral Tōgō, commander of the Japanese battleship fleet, had achieved this against Admiral Zinovy Rozhestvensky's Russian battleships in 1905 at the Battle of Tsushima, with devastating results. Jellicoe achieved this twice in one hour against the High Seas Fleet at Jutland, but on both occasions, Scheer managed to turn away and disengage, thereby avoiding a decisive action.
