The Battalion’s right boundary was defined by the Minsmere New Cut-sluice and the left hand boundary the River Blyth. The battalion area was divided in to two half areas – Dunwich and Walberswick.
The area Walberswick-Dunwich comprises of shingle and sand beach with marshes behind and high ground to the west of Walberswick. Dunwich-Minsmere Cliffs are dominated by 100 ft cliffs, impassable to AFV’s and difficult for infantry. Minsmere Cliffs-Minsmere Sluice is characterized by a shingle and sand beach with flooded marshes behind extending as far back as Eastbridge.
During normal conditions, guards were to be placed by all companies at dawn and dusk. Patrols, with the intention of preventing any persons landing on the coast, were also to be made between dawn and dusk as follows:
A company: Minsmere Sluice to Dunwich RDF station
B Company: Dunwich RDF Station to Little Dingle
D Company: Blythburgh/Walberswick cross roads to Watermill House
C Company: Watermill House to River Blyth
On receipt of “Stand to” the following actions were to be taken:
1) All warning signs to be removed from minefields
2) Road blocks to be put in place and manned. East of the Back Line they were not to be removed unless ordered by Brigade HQ. West of the Back Line, they could be removed once troops were certain they could be replaced at short notice.
3) All battle positions to be fully manned
4) Battalion HQ to move to Sallow Walk Covert
5) All troops to carry arms and ammunition at all times.
On receipt of “Action stations”, the second in command will move to Greyfriars, Dunwich to command Dunwich half area in case of communications being cut with battalion HQ. Battalion intention was to deny Minsmere Cliffs, Dunwich and Walberswick to the enemy.
A Coastal Defence Battery (371 Battery) was in the battalion area at Sandymount Covert which also formed a defended locality. Its personnel would come under the command of the Battalion if it could no longer perform its Coast Defence role. The battalion was also supported by machine guns from “D” Coy 1/7 Middlesex Regt.
All local commanders had the authority to order road cratering and bridge demolitions with the exception of demolitions and road craters at Halesworth and the River Blyth road bridges, which could only be fired on brigade orders.
D Troop was to maintain a mobile anti-paratroop platoon to deal with enemy paratroops at any location within the battalion boundary. This was to consist of four vehicles (one for the commander and one for each section) and was to be armed with one 2” mortar, three LMG’s, three Thompson sub-machine guns and rifles and grenades.
Home Guard troops in the battalion area included 34 and 36 platoon, 8th Battalion and “C” company, 4th Battalion. These troops were responsible for three Garrison towns/villages in the area: Halesworth, Westleton and Blythburgh as well as for the blocks and demolitions along the Back stop-line. A continuous anti-tank and wire obstacle was planned for Westleton Garrison but was never completed. The commander of the Halesworth Garrison had 5,000 anti-tank mines at his disposal. The following was the required level of troops and fire power required for the Halesworth Garrison compared with the actual available:
Men MG Light MG Thompson smg Northover projector
