Ok - how did I fail to notice this was on????
A two part Channel 5 documentary that combines two of my favourite subjects - military history and archaeology. A very very big archaeological dig on a massive trench system in the vicinity of Messines, scene of some very heavy fighting in 1917 and the detonation of some massive mines.
Some of the finds are stunning - shells with time fuzes, incredible trench earthworks, stashes of German grenades....
Part 1 is available online here.
Part 2 is available online here.
