"Von der Tann" and "Moltke" changed their speed and direction, which threw off the aim of the V Battle Squadron and earned the battered ships a short respite. While "Moltke" and "Von der Tann" were drawing the fire of the V Battle Squadron battleships, "Seydlitz" and "Derfflinger" were able to concentrate their fire on the British battlecruisers; between 17:25 and 17:30, at least five shells from "Seydlitz" and "Derfflinger" struck "Queen Mary", causing a catastrophic explosion that destroyed the ship. "Moltke"s commander, "Kapitän zur See" von Karpf, remarked that "The enemy's salvos lie well and close; their salvos are fired in rapid succession, the fire discipline is excellent!"
