End of the line

In World War 2 the Western Command Stop Line No.6 ran from Tamworth via Trent Valley, E side of Stoke-on-Trent, to Macclesfield and Stockport, thence to 6 miles SE of Manchester. This line of fortifications was designed to resist an invasion force coming from the east. Here in Tamworth, close to the River Tame, is this pillbox close to the start of the line.
