On June the 21st 1948 the M.V. Empire Windrush sailed in to Tilbury docs with the first post-war Caribbean migrants workers which is well documented. Less known is the story of 66 Polish passengers that boarded ship in Mexico, women and children displaced from Poland. Their epic journey started in 1940 when the soviets deported hundreds of thousands Polish citizens in to the depths of Siberia.
In 1941, after Germany turned and attacked Russia the Soviets became our allies and joined the West in fighting the Germans. For a few months there was a brief amnesty and the imprisoned Poles were released and, under the leadership General Anders, formed the Second Corps of the Polish army.
There is a detailed list of all 66 passengers, with their addresses in various camps in UK. They were mostly women, many in their 40s, and a bunch of kids of both sexes. The youngest were two eight-years-olds; that would make them 72 years old now, if they are still alive.
