in a letter to British Foreign Secretary dated 1 February 1915. Fifty-two of the 2000 prisoners volunteered for the Brigade. Contrary to German promises, they received no training in the use of machine guns, which at the time were relatively new and unfamiliar weapons. During World War I, Casement is known to have been involved in the German-backed plan by Indians to win their freedom from the British Raj, the "Hindu–German Conspiracy", recommending Joseph McGarrity to Franz von Papen as an intermediary. The Indian nationalists may also have followed Casement's strategy of trying to recruit prisoners of war to fight for Indian independence. Both efforts proved unsuccessful. In addition to finding it difficult to ally with the Germans while held as prisoners, potential recruits to Casement's brigade knew they would be liable to the death penalty as traitors if Britain won the war. In April 1916, Germany offered the Irish 20,000 Mosin–Nagant 1891 rifles, ten machine guns and accompanying ammunition, but no German officers; it was a fraction of the quantity of the arms Casement had hoped for, with no military expertise on offer. Casement did not learn about the Easter Rising until after the plan was fully developed. The German weapons never landed in Ireland; the Royal Navy intercepted the ship transporting them, a German cargo vessel named the Libau, disguised as a Norwegian vessel, Aud-Norge. All the crew were German sailors, but their clothes and effects, even the charts and books on the bridge, were Norwegian. As John Devoy had either misunderstood or disobeyed Pearse's instructions that the arms were under no circumstances to land before Easter Sunday, the Irish Transport and General Workers' Union (TGWU) members set to unload the arms under the command of Irish Citizen Army officer and trade unionist William Partridge were not ready. The IRB men sent to meet the boat drove off a pier and drowned. The British had intercepted German communications coming from Washington and suspected that there was going to be an attempt to land arms at Ireland, although they were not aware of the precise location. The arms ship, under Captain Karl Spindler, was apprehended by HMS Bluebell on the late afternoon of Good Friday. About to be escorted into Queenstown (present-day Cobh), County Cork on the morning of Saturday 22 April, Captain Spindler scuttled the ship by pre-set explosive charges. Its surviving crew became prisoners of war. Landing
