The Sinking of the Lusitania (1918) is an American silent animated short film by cartoonist Winsor McCay. It is a work of propaganda re-creating the never-photographed 1915 sinking of the British liner RMS Lusitania. At twelve minutes, it has been called the longest work of animation at the time of its release. The film is the earliest surviving animated documentary and serious, dramatic work of animation. The National Film Registry selected it for preservation in 2017.
On 7 May 1915, a German submarine (SM U-20) torpedoed and sank the RMS Lusitania near Ireland; 128 Americans were among the 1,198 dead. The event outraged McCay, but the newspapers of his employer William Randolph Hearst downplayed the event, as Hearst was opposed to the U.S. joining World War I.
