On the 1 September 2004, at the Beslan siege in Russia when Chechen terrorists took more than 1,000 people captive at celebrations held to mark the first day of the school year. Lasting three days, the siege reached a bloody climax when two bombs exploded inside the school and Russian troops stormed the building, sparking a fire in the gymnasium where the captives were held. In the chaos, 334 hostages, more than half of them children, died. Never a war correspondent, Tom was emotionally pulverised, and his solution was to turn back to his lifelong love of walking, to a nature cure of sorts. Having long loved the Caucasus, he also wanted to understand why the mountain peoples there, people like the Chechens, were so angry at Russia. That was how Tom came to walk 1,000 miles across the North Caucasus.
