All wars have elements of attrition in them – like it or not. Battles of attrition are not linear either, they depend – to a large extent – on battlespace geometry. Peter is joined by Dr Jack Watling for one of their monthly chats – this time about attrition, from the 19th Century to today. Their conversation turns covers themes of people, leadership, logistics, casualties, ideation, and time, and how each of these relate to the realities of combat attrition, wars of attrition, and strategies of attrition. And as always, they remind us that the enemy gets a vote too.
