Continued mapping at Westleton today. Had a good look at the second dugout with concrete roof, not sure if I did not look properly the first time but today got a good idea how it was constructed. Basically a 'L' shaped trench was dug, revetted with corrugated sheets and 2" poles which were windlassed. The 10" concrete roof was constructed on site with 6x1 wood shuttering (at least from the bottom) which is clearly visible. Have attached some photos along with a Google sketchup cross-section. I had to limit the recording today as I am collecting data far faster than I can process. Hence took the opportunity to have a good stomp around and found yet more earthworks! Many hours of mapping to go yet!
Well at the end of the week off to the Somme for eight days. Hope to post some blogs on this trip even though its not within the remit of this project, so if you follow this blog, don't panic if you find yourself reading about WW1 in the next few posts.
