Some of the surviving practice trenches

The earthwork remains of a quarter-scale trench system survives on the Chase. The system is made up of a series of zig-zag trenches similar to those seen on the Western Front and was thought to have been dug for training troops based on the chase. A recent archaeological survey has identified further, extensive trench systems survive across the Chase dug in the familiar 'Greek Key' and zig-zag patterns.
