The story of Jugroom Fort takes a step back in time to the eve of battle.

January 2007. The battle-hardened Royal Marines of Zulu Company assemble ahead of a massive air bombardment of the target, a notorious Taliban stronghold. Their orders include the possibility of crossing the Helmand River and attacking on foot. At 5am - that order is given. They're going in.

Captain Chris Witts commands the amphibious Viking vehicles. As the treacherous crossing is made, the marines ready themselves.

As they launch their attack, they discover that despite a night of heavy bomging - Jugroom Fort is far from deserted.

Lance Corporal Glyn Sadler and Company Sergeant Major Shep Shepherd describe the switch from eerie silence - to an intense firefight.

The Fort is told solely by current and former members of the Armed Forces. Many are speaking for the first time.
