The cargo included 4,200,000 rounds of Remington .303 rifle/machine-gun cartridges, 1,250 cases of empty 3 inches fragmentation shell casings and eighteen cases of percussion fuses, all of which were listed on the ship's two-page manifest, filed with US Customs after she departed New York on 1 May. However, these munitions were classed as small arms ammunition, were non-explosive in bulk, and were clearly marked as such.
