In 2006, British forces entered the Helmand Province of Afghanistan in what would become one of the defining military campaigns of the decade. At great cost in blood and treasure, the UK waged a protracted counter-insurgency against a resurgent Taliban.

Former generals, politicians and civil servants contribute to an original RUSI analysis that provides a startling insight into the decision to commit the UK to a war - a decision wracked by conflict, incoherence and confusion.
