In 2006, the ISAF mandate was expanded to include the restive provinces of southern Afghanistan. Helmand became the responsibility of a primarily British unit,
Task Force Helmand. Due to his involvement in the
opium trade and links with the insurgency, the British insisted that Governor Akhundzada be removed from his post. His replacement, engineer
Mohammad Daoud lacked local support, and as Akhundzada's militias had become inactive, the Taliban hastened to fill the power vacuum, and the situation rapidly deteriorated. On May 18, 2006, insurgents attacked the
Afghan National Police (ANP) force in Musa Qala, killing 20 policemen. The British
Pathfinder Platoon was deployed to Musa Qala for five days to assist the police before being replaced by an American unit. On June 14, they were ordered to return to Musa Qala. The 25-man Pathfinder Platoon, commanded by Major Nick Wight-Boycott, was primarily a mobile
reconnaissance unit, and thus were not best suited for garrison duties. However, the Battle Group's resources were already stretched and there were no other units available. The Musa Qala district centre was a cluster of low cement and mud buildings surrounded by a 10-foot wall. Situated in the middle of the town, it housed the local police headquarters, a prison and a clinic built by the Americans. The Pathfinders took over a building in the center of the compound and emplaced three
sangars (fortified posts), with one on the roof of their building, one facing east towards the market, and one on a building just outside the compound walls. The tallest building in the district centre was the prison, which was soon nicknamed "
the Alamo" by the Pathfinders, who sited a
.50 calibre machine gun on its roof. An 80-man Afghan National Police detachment also garrisoned the district centre. The ANP were hated by the local population, who accused them of thievery and
pedophilia. The police in Musa Qala were, the British noted, undisciplined and slack about their duties, but they were also more than willing to fight the insurgents. Two weeks after the arrival of the Pathfinders, an American convoy was ambushed in the nearby green zone, and several vehicles were lost. The Americans responded with massive
firepower, including an airstrike from a
B-1 bomber and attacks by
AH-64 Apache helicopters. Following this incident, the population of Musa Qala began to flee and British intelligence suggested the Taliban had encircled the district centre. However, on the next day, coalition jets conducted low-level flyovers over the town, and no Taliban attack occurred, though some small arms fire struck the base. The Pathfinders were joined by 6 Platoon, B Company,
3 PARA (the Guards Parachute Platoon), freeing them to conduct patrols through the town, and by July 1, the population had gradually returned to their homes. On July 6, the Pathfinders were scheduled to be replaced by G battery,
7 Para RHA, who were supposed to drive into Musa Qala through the green zone. The Pathfinders escorted the ANP contingent in their
Land Rover WMIK in order to secure the route, but when they were fired upon by insurgents, the policemen broke formation to engage their enemies, and the operation broke down in confusion. After a similar attempt on the next day also failed, the Guards Parachute Platoon were flown out and a mixed force of 20 gunners from I Battery, 7 RHA, 15 engineers, five Danish and ten
Afghan National Army (ANA) soldiers were flown in. The engineers were put to work consolidating the defenses of the base with locally-purchased materials. ==The siege==
