RMS Lusitania arrives New York City 1907 Postcard

RMS Lusitania was an ocean liner owned by the Cunard Line and built by John Brown and Company of Clydebank, Scotland, torpedoed by a German U-boat on 7 May 1915. The ship sank in 18 minutes, eight miles (15 km) off the Old Head of Kinsale, Ireland, killing 1,198 of the 1,959 people aboard. The sinking turned public opinion in many countries against Germany. Though it carried some US citizens, it was not instrumental in bringing the United States into World War I. It is considered the second most famous civilian passenger liner disaster, after the sinking of the RMS Titanic. The sinking of the Lusitania caused great controversy, which persists to this day. In the aftermath of the sinking, the German government tried to justify it by claiming in an official statement that she had been armed with guns, and had "large quantities of war material" in her cargo.They also stated that since she was classed as an auxiliary cruiser, Germany had had a right to destroy her regardless of any passengers aboard, and that the warnings issued by the German Embassy before her sailing plus the 18 February note declaring the existence of "war zones", relieved Germany of any responsibility for the deaths of American citizens aboard. While it was true that the Lusitania had been fitted with gun mounts as part of government loan requirements during her construction, to enable rapid conversion into an Armed Merchant Cruiser (AMC) in the event of war, the guns themselves were never fitted. However, she was still listed officially as an AMC. Her cargo had included an estimated 4,200,000 rounds of rifle cartridges, 1,250 empty shell cases, and 18 cases of non-explosive fuses, all of which were listed in her manifest, but the cartridges were not officially classed as ammunition by the Cunard Line. Various theories have been put forward over the years that she had also carried undeclared high explosives that were detonated by the torpedo and helped to sink her, but this has never been proven.
