Thanks for the excellent summary, Stephen. I've only recently realised just how important this battle was in the story of WW1, and in particular the significant part the Tank Corps played in it. The tankies were actually 'sacrificial lambs' during this 3-day battle, as all the enemy firepower was directed at them rather than the infantry. There are documented instances of infantry officers threatening to shoot tankies if they chose to retreat (for sound operational reasons - no failure of morale), as the distraction they offered was too valuable. So they stood, did their duty, and died anyway. Men of Iron.
I've just got back from Bovington, where the event was commemorated. The historical highlight was that the four Victoria Crosses won by Tank Corps officers in WW1 (all posthumously) were brought together in one place for the first time ever - one (Sewell) held by the Tank Museum, one (West) lent by the Ashcroft Collection (the largest collection of VC's in the world), and the other two (Robertson and Wain) lent by the original families who still treasure them. I believe they're on display until November if you want to make a pilgrimage.
From the Armortek perspective, the 'Band of Brigands' turned up trumps ! We had 5 working Mark IV's present (Steve, Daniel, Pete, Brian Clay and myself) as well as Adrian's part-built one which drew as much attention as the finished models - the public were fascinated to see how they all went together ! The trench system was set up again (
thanks, Denny), which looked so much better than a bare tarmac car park (although I'm not sure Bovington will store it for much longer, unfortunately). And the weather was kind - cooler than of late, but without the thick fog of 100 years ago.
Stupidly, I forgot to take my camera ! Fortunately, Daniel took loads of photos, so I'll leave him to put up the best of them, including the obligatory group shot.
Many thanks to the 'Band of Brigands' for commemorating this important event in style, and to Fiona (Steve's wife) for adding a welcome touch of glamour, class and decorum

.
All the best,
Chris
