The Battlegroundpodcast on the wars of the 20th century, said presenter Saul David happily, ‘will have lots of bombs and bullets but we’re also interested in other aspects of conflict: social, political and cultural’. He’s a military historian. His co-presenter, Patrick Bishop, went on: ‘Alongside the personalities, the battles and the technology – and there will be plenty of that, we promise – expect to hear some thought-provoking stuff that puts conflict into its wider context.’
