2006, a scratch British Army company of about 85 men, two platoons of Royal Irish Rangers and a platoon of mainly Parachute Regiment soldiers hold an Afghan compound in the village of Musa Qala in Helmand Province against hundreds of Taliban insurgents in a 50 day siege. The British troops had few heavy weapons (two heavy MG's an 81 mm mortar and a couple of light mortars) and their position was surrounded by buildings providing cover for the enemy. They had only very limited air support.

The town was recaptured by British and Afghan forces in late 2007.
Recently the Taliban recaptured Musa Qala from the Afghan Army...
