Yesterday's Witness (1969)

21 March 1945: the date of one of the RAF's most daring and difficult low-level raids. The target: Shell House in the centre of Copenhagen, which the Gestapo had commandeered as their headquarters. Here they were collecting more and more damaging information about the Danish Resistance which was in danger of being wiped out. To destroy the Gestapo records meant precision bombing at its most accurate, for not only was Shell House in the middle of a heavily populated area but the Germans had put captured Resistance leaders in cells on the top floor - as hostages against possible attack from the air. Air Chief Marshal Sir Basil Embry, other senior RAF officers who took part in the raid and wartime members of the Danish Resistance tell of the success - and tragedy - of that day.

The Spanish Civil War, in the late 30s, could be said to be the first of the ideological wars of our time. Nazi Germany and fascist Italy used Spain as a rehearsal ground for the greater war to come. Thousands of volunteers poured into Spain to take up arms on the other side against Franco. Of the 2,000 volunteers who went from Britain, 500 were killed. The members of the British Battalion of the International Brigade were mainly workers: railwaymen, miners, trades unionists. In this programme they - and others who supported them - tell the story of the Civil War as they saw it. Taking part: Claud Cockburn, Bob Cooney, Tony Gilbert, Margaret Lesser, Wil Paynter, Jim Prendergast, Bessie Wild and Sam Wild

The extraordinary story of a teenage girl on the run from the Gestapo in wartime Europe. One sunny day in May 1940 the 16-year-old Gergana Taneva was out walking with some friends 'when suddenly there were screams of German voices and we found that the street from all sides was closed. A big lorry drove in front of us and then another and another one. We were panic-stricken. We started to run...' It was the start of a five years' nightmare.

By the end of the First World War the Isle of Lewis, with a population of only 30,000, had lost 800 men in land and sea battles throughout the world. And then this Hebridean island was dealt the heaviest blow of all. A further 200 men, nearly all of them natives of Lewis, died in one night - a few weeks after the war, after the fighting had stopped. In the early hours of 1 January 1919, in a rising storm and pitch darkness, the Admiralty yacht Iolaire, carrying naval ratings home on New Year's leave, was wrecked right at the mouth of Stornoway harbour, right on the shores of the Isle of Lewis itself. One man, John F. Macleod, managed to swim ashore with a rope and altogether some 70 men were saved. In this programme Macleod, some of the other survivors, and men and women of Lewis tell the story of that tragic night.
