Has Hannibal's route across the Alps been uncovered? Scientists use 2,000-year-old trail of dung to track legendary general

Hannibal's 30,000-strong army trudged through deep snow in the grip of winter in 218BC with more than 15,000 mules and horses before crossing into Italy where they nearly made it to the gates of ancient Rome.
But, according to experts, such a large movement of men and animals must have left what they describe as a "mass animal deposition event".
And at a patch of swampy ground near the Col de la Traversette, a narrow pass between Grenoble in France and Turin in Italy, they think they have found it in an unusual layer of muck about 16in beneath the surface.
In a blog post, Chris Allen, a senior lecturer in environmental microbiology at Queen's University Belfast, said: "Using a combination of microbial genetic analysis, environmental chemistry, pollen analysis and various geophysical techniques, we unveiled a mass animal deposition of faecal materials – probably from horses – at a site near the Col de Traversette.
