I watched numerous bombing waves from a ridge overlooking the Amu Darya river that runs along Afghanistan’s northern border with Tajikistan and Uzbekistan. It was towards the end of last October, as the anti-Taliban coalition (read the Americans) stepped up the air campaign in support of the Northern Alliance (NA) forces. The hill-top was a natural frontier that protected the troops loyal to the former president Burhanuddin Rabbani and his military commanders from the Taliban. But the defensive positions also boxed them into a relatively narrow wedge of territory in the north-east of the country.
