After two tours of Iraq as a soldier, I spent six months in Afghanistan in 2007 as part of Operation Herrick VI. My deployment came a year after the then Defence Secretary, John Reid, said we would be ‘perfectly happy to leave the country in three years’ time without firing one shot’. However, the very first night I arrived in Lashkar Gah, the capital of Helmand, troops were battling the Taleban across the province, with thousands of shots fired every day. Plans were being made about how we would evacuate our camp if it was overrun. Today, 14 years on, as the final US troops depart, left behind are more than 47,000 dead Afghan civilians, more than 3,500 dead soldiers from the coalition, and a country on the cusp of civil war.
