SS Brussels

On 28 March 1916, U-33 ordered the Great Eastern Railway's SS Brussels to stop.[5] Instead of stopping, her captain, Charles Fryatt ordered full steam ahead and attempted to ram U-33, which only just managed to dive in time.[6]

Sinking of hospital ship

On March 30,[7] 1916 the Russian hospital ship Portugal was towing a string of small flat-bottomed boats to ferry wounded from the shore to the ship. Off Rizeh, on the Turkish coast of the Black Sea she had stopped as one of the small boats was sinking and repairs were being made. The ship was not carrying wounded at the time, but had a staff of Red Cross workers on board, as well as her usual crew.[8] | The ship's crew saw a periscope approaching the vessel but as the ship was a hospital ship and protected by the Hague conventions no evasive actions were taken. Without warning SM U-33 fired a torpedo which missed. The submarine came around again fired a torpedo from a depth of 30 feet, which hit near the engine room, breaking the ship into two pieces.[8] Of 273 persons on board, 158 were rescued.[9]
