It is not generally known that the German submarine fleet surrendered on the banks of Lough Foyle and now lies at the bottom of the sea near its entrance, or that the Bismarck was spotted by a plane stationed at St Angelo Airport in County Fermanagh, or that Northern Ireland was the first place in Europe to host American troops.President Roosevelt is recorded to have said that the Allies could not have won the Second World War without the contribution made by Northern Ireland. Memory of that contribution, and the human cost, is faithfully recorded here for the first time, after numerous interviews with a range of people who have stories to tell.
