Jack Jones and the Spanish Civil War

Further to Iain Dale's post on the Trade Unionist Jack Jones who died aged 96, yesterday. Jones also fought for the Republicans in the Spanish civil war. He may have been 'one of the great trade unionists of his time' as Paul Burgin describes him (here) but did he ever regret the atrocities committed by the Republicans, for example, against the Catholic Church, in the civil war? I very much hope so.

Of course, the Nationalists committed atrocities as well. Neither side, therefore, fought justly in that war and no one who supported them without qualification can really be acclaimed a hero. With that said, requiescat in pace.
