However, the ship was not armed for battle and was carrying thousands of civilian passengers, and the British government accused the Germans of breaching the cruiser rules. The sinking caused a storm of protest in the United States because 128 American citizens were among the dead. The sinking shifted public opinion in the United States against Germany and was one of the factors in the declaration of war nearly two years later. After the First World War, successive British governments maintained that there were no munitions on board "Lusitania", and the Germans were not justified in treating the ship as a naval vessel. In 1982, the head of the Foreign Office's American department finally admitted that, although no weapons were shipped, there is a large amount of ammunition in the wreck, some of which is highly dangerous and poses a safety risk to salvage teams.
