Far from it. The secret army was trained to let the invaders roll over them, and then emerge to create chaos in the rear supply area of the German’s.
Many were local landowners and knew their home area extremely well.

I am curious about the role of the secret army based at Coles Hill near Highworth.
Please correct me if I am wrong, but I have always believed that they were basic Dads army recruites specially trained for their covert role, and nothing to do with the regular army.

I live in Devizes and walk my Dog down a pathway adjacent to the canal, around a pillbox, over the bridge and down the Canal. This particular one is sealed up. The one in Horton is probably the next one down the line. Interesting stuff!

Good point. I guess the idea persists because the regular Army was only manning the defences briefly. I imagine the pressure was on to get many of them re-equipped, re-trained, re-organised and into the defence lines quickly after their return from Dunkirk at the height of the threat of invasion. So the public would have been aware of reserves & Home Guard manning the lines initially, and then again as the threat subsided.

The Home Guard were initially responsible for reporting the location of paratroops, operating roadblocks and in some cases defending smaller nodal points. By the time the Home Guard took responsibility for defending defended localities, anti-tank islands and further nodal points the GHQ line had been disbanded, with many of the remaining pillboxes being incorporated into anti-tank island, nodal point and vulnerable point defence schemes.
