The Welsh Cavalry: Last Tour of Afghanistan

For nine years BBC Wales journalist Gareth Jones has been following the Queens Dragoon Guards - The Welsh Cavalry - as they take on insurgents in Iraq and Afghanistan. He's been with the same small group of soldiers as they endure extreme conditions, get ambushed by the Taliban and lose comrades to roadside bombs. In this programme he's back with them for their final tour of duty in Helmand Province. Their job is to defend Camp Bastion in the months before final withdrawal. As he discovers, the Taliban are still intent on causing as many casualties and as much damage as possible before the British depart.
