] I'll trawl through my library and post up any events I think are particularly notable, which I hope you'll find interesting. I know that Steve Stuart is keen to commemorate some of these by displaying our Mark IV's if we can 
. [Gill - would it be possible to make this a 'sticky', so it always appears at the top of the Mark IV forum ?]
I missed this one, on the Tank Museum's Facebook page relating to 'Little Willie':
However, there's another one on 22 September that is worthy of note. 'Little Willie' was only a prototype, and it was quickly appreciated that it would never cope with the conditions of the Western Front. In particular, there were major problems with the track design. So William Tritton (of Fosters of Lincoln) and Lieutenant Walter Wilson RN (both deemed in 1919 to be the official inventors of the tank) set to work to design a better system.
On 22 September 1915 Tritton sent the following cryptic telegram to Albert Stern (then Secretary to the Landships Committee):
"Balata [a track design by Balata Belting] died on test bench yesterday morning. New arrival by Tritton out of Pressed Plate. Light in weight but very strong. All doing well, thank you. Proud parents."
In his book "Tanks 1914-1918: The Log-Book of a Pioneer", Stern simply states "This was the birth of the Tank".
So this is where it all started ............
All the best,
Chris
