Almost immediately, the crew scrambled to launch the lifeboats but the conditions of the sinking made their usage extremely difficult, and in some cases impossible due to the ship's severe list. In all, only six out of 48 lifeboats were launched successfully, with several more overturning and breaking apart. Eighteen minutes after the torpedo struck, the ship's trim levelled out and she went under, with the funnels and masts the last to disappear. Of the 1,962 passengers and crew aboard "Lusitania" at the time of the sinking, 1,198 lost their lives. In the hours after the sinking, acts of heroism amongst both the survivors of the sinking and the Irish rescuers who had heard word of "Lusitania"s distress signals brought the survivor count to 764, three of whom later died from injuries sustained during the sinking.
