Most of the fighting involving British troops occurred along the Western Front where Germany met France and Britain. The other big front, the Eastern Front, was where Germany lined up against Russia.
The Western Front was a 700 kilometer-long line of trenches, and barbed wire that stretched from the English Channel to the Swiss frontier.
Within a year, the entire Western Front resembled a barren moonscape where nothing lived except soldiers – and rats. The former towns, villages and forests had been shelled to smithereens.
