The Royal Marines Commandos have launched their ground assault on Jugroom Fort.

A jagged, v-shaped hole has been blasted into its side, and fresh from a nerve-wracking river crossing, the men of Zulu Company surge from their Viking vehicles to take up positions and press home their assault.

This will be the location for "the break-in", the moment of any attack on an enemy encampment when the defences are breached.

5 Troop are the tip of the spear. Commanded by Al Weldon, Rifleman Marine Mike Cleary is "point man" - leading the way.

Speaking for the first time about their experiences, Al and Mike describe the moment the eerie quiet of a seemingly deserted stronghold is shattered.

Overwhelmed by enemy fire, Zulu Company regroup and attempt to marshal their casualties from the "killing ground".

Last to leave, Company Sergeant Major Shep Shepherd describes last-ditch efforts to account for their missing man.

Senior Marine, Lance Corporal Mathew Ford cannot be found. And as the enemy fire continues around them difficult decisions are made to ensure the safety of the rest of the company.

The Fort is told solely by current and former members of the Armed Forces.
