The British Army in the Second World War is often judged through the lens of manpower shortages and a sense of being overstretched. Critics point to a force spread across too many theatres and suggest that this inevitably limited its effectiveness.

But is that a fair assessment of an army that expanded from a few hundred thousand men into a global fighting force of over eight million, operating across Europe, North Africa, the Mediterranean, and the Far East?

In this episode, I am joined by Brian Walter to explore his argument that the British and Commonwealth armies emerged from the legacy of the First World War as a reduced force, entered the Second World War underprepared, but went on to adapt, expand, and ultimately play a decisive role in defeating Germany, Italy, and Japan across multiple theatres of war.
