By late-April, the First Squadron included "Vengeance", seven other battleships, and four cruisers, and was commanded by Rear Admiral Rosslyn Wemyss. The First Squadron was tasked with supporting the Landing at Cape Helles, which took place on 25 April. "Vengeance" and the battleship were initially assigned to support the landing at Morto Bay, taking up their firing positions at 05:00 and opening fire at Ottoman positions in the heights around the bay shortly thereafter. "Lord Nelson" was later sent to support other landing beaches further south on the peninsula, and "Vengeance" was joined by "Prince George". As the allied ground forces advanced on Krithia, "Vengeance" and several other battleships provided fire support, though the Ottomans blocked the attack in the First Battle of Krithia.
