Rostron ordered the ship's heating and hot water cut off in order to make as much steam as possible available for the engines, and had extra lookouts on watch to spot icebergs. Cottam, meanwhile, messaged the "Titanic" that the "Carpathia" was coming as quickly as possible and that they expect to reach their location within four hours. Cottam refrained from sending more signals after this, trying to keep the network clear for the "Titanic"s distress signals. The "Carpathia" reached the edge of the ice field by 2:45 a.m., and for the next two hours dodged icebergs as small growlers of ice ground along the hull plates. The "Carpathia" arrived at the distress call's position at 4:00 a.m., approximately an hour and a half after the "Titanic" went down, claiming more than 1,500 lives. For the next four and a half hours, the ship took on the 705 survivors of the disaster from "Titanic"s 20 lifeboats. Survivors were given blankets and coffee, and then escorted by stewards to the dining rooms. Others went on deck to survey the ocean for any sign of their loved ones. Throughout the rescue, the "Carpathia"s own passengers assisted in any way that they could, offering warm food, beverages, blankets, accommodations, and words of comfort. By 9:00 AM, the last survivor had been picked up from the lifeboats, and Rostron gave the order to sail away from the area. "SS Birma" was nearby and offered "Carpathia" supplies but was told to "shut up" by their wireless operators due to "Birma" not using a Marconi wireless set.
