The Taunton Stop Line was a World War II defensive line in south west England. It was designed "to stop an enemy's advance from the west and in particular a rapid advance supported by armoured fighting vehicles (up to the size of a German medium tank) which may have broken through the forward defences."
The Taunton Stop Line was one of more than 50 similar defensive lines that were constructed around England, all designed to compartmentalise the country to contain any breakthrough until reinforcements could arrive. Stop Lines used a combination of geography and construction to make continuous defences. The innermost and longest was the GHQ Line. They were constructed as part of a package of field fortifications planned under the leadership of General Sir Edmund Ironside, the newly appointed Commander-in-Chief, Home Forces.
The Taunton Stop Line ran north-south for nearly 50 miles (80 km) through Somerset, Dorset and Devon, roughly from Axminster to Chard along the River Axe, then along the Great Western Railway to Ilminster, the railway and Chard Canal to Taunton, the Bridgwater and Taunton Canal to Bridgwater, and the River Parrett to the coast near Highbridge. Highbridge was also the starting point for the east-west GHQ Line.
