This is not really relevant, but if a programme showing Richard Harrington (of Y Gwyll fame) following his grandfather's footsteps to Spain and learning of the unequal conflict between Dictator Franco, supplied and financed by fellow fascists in Germany and Italy, and ordinary Spanish folk with volunteers from many countries armed with relics from WW1 or even the Napoleonic Wars, if this programme ever gets made in Welsh, it is well worth watching. Clearly I do not personally remember the Spanish Civil War of 1936-37, but I knew exiles still living in UK until Franco died in 1973, if not longer, still mourning for democracy in their homeland.
The programme I watched, recorded from BBC2 Wales on Saturday evening is probably still available on iPlayer. "Richard Harrington: My Grandfather's War."
I was ashamed that my own dad, born in September 1917, waited until 1938 to join up ready to fight fascism. but of course, you were not 'adult' in those days until you were 21, so maybe his family could have stopped him going to Spain, which the British Government had forbidden Brits to do!!
