The Russian Embassy honoured 11 local World War Two veterans at a ceremony at Lancaster Town Hall for their part in transporting crucial supplies to Russia.
The veterans were awarded the Ushakov medal by the Russian Naval Attaché, Captain Oleg Kornienko.
The Russian embassy said the convoys allowed Russian soldiers to defeat the Germans on the Eastern Front.
More than 3,000 men died during the maritime campaign that Winston Churchill was said to have called the “worst journey in the world”.
The Russian Embassy wrote to survivors in May 2012 that it intended to award them with the Medal of Ushakov as a symbol of the country’s gratitude. The Ushakov medal is awarded to sailors who have displayed courage in the course of defending Russia or its interests.
