"Iphigenia" arrived at Murmansk in March 1917, just as the Russian Revolution was beginning. She operated out of Archangel in the summer when the White Sea was clear, and from the ice free Murmansk in the winter. Although it was apparent to local Allied commanders that the materiel landed after the spring of 1917 was not being put to good use, their advice to stop the flow was ignored by Whitehall. Indeed, much of the materiel was either destroyed or ended up being used by the Bolsheviks or the Germans.
