How big was the Britain's army in World War 1?

Answer 1

At the onset of World War I in 1914, Britain's army consisted of about 250,000 regular soldiers. However, as the war progressed, the British Army expanded significantly through conscription and enlistment, reaching a peak strength of around 5 million personnel by the war's end in 1918. This massive increase was driven by the need to replace heavy casualties and maintain the fight on multiple fronts.
