Part of the 'History of Warfare' series, this documentary looks at the events surrounding Napoleon's ill-judged invasion of Russia in 1812. Entering the country with the largest invasion force the world had yet seen - some 650,000 men - Napoleon defeated the Russian army in key encounters such as the Battle of Borodino. But as the French progressed further into the vast Russian interior, it was to be the weather, not force of arms, that defeated them. After taking Moscow, Napoleon was forced into a brutal and ignominious retreat that saw tens of thousands of his men perish in the freezing Russian winter. Featuring period imagery, dramatised 'eye witness' accounts, expert comment and analysis, and extracts from the Russian film of 'War and Peace'. Narrated by Robert Powell.
