"Coming south and only seven kilometres north of the Sangin District Centre, home to the District Governor, is Forward Operating Base Inkerman, home to the men and women of B Company. FOB Inkerman is critical to interdicting the routes of the enemy as they try to infiltrate into Sangin from the enemy bases in the Upper Sangin Valley.
"B Company has fought fiercely with a tenacious enemy who combine improvised explosives with small arms fire ambushes.
"Sangin DC and the town centre was protected by A Company, the Afghan National Army and the Afghan National Police, all based out of FOB Jackson, which sits on the banks of the wide-flowing Helmand River.
"Here, military operations seek to protect the people and prevent the enemy from getting its grip on the town centre.
"A British Stabilisation Advisor works shoulder to shoulder with the Afghan District Governor, one of the local tribal elders, to improve the day to day lives of the Afghan people.
"FOB Wishtan, just to the east of Sangin, where C Company lived, guards the eastern approaches to Sangin. Like the rest of Sangin, it is a place strewn with IEDs and all movement is dangerous. We have been fighting a battle of wills with the enemy here and gradually we have been able to increase our control of the area and our freedom of movement.
"Finally, FOB Nolay, my most southern base, guards the southern route into Sangin, vital to our own resupply but also provides a commercial lifeline for the bazaar in Sangin.
"Conditions have been refreshingly basic (austere is the posh word). There are no soft mattresses, no hot showers for the mornings or nights, the most basic toilets you've ever seen and very little fresh rations. But one gets used to a simple and basic existence very quickly.
"The heat was the hardest thing to get used to - one could never drink enough and I am not sure I need to eat pasta for a while!
"But the true test is whether we have left Sangin a better place. For me, progress in Sangin has not been dramatic but we have moved forward, indelibly so. We will definitely leave Sangin in a better state then when we found it.
