Kent Group 4 "Grape Group"

Groups 4 and 9 were under the Area Command of Captain Marchant of Guilton, Ash. Group 4 had the code-name "Grape".

In his book; The Invasion That Never Was, Douglas Welby (2012) had discovered, recorded and photographed a two level OB near Ash. This was not recognised by Auxilier Chambers of Ash Patrol. Welby thinks it may have been built as a central hide for all Patrols in the area.
