Darell's Battery

Darell’s Battery is situated approx 50 yards South-west of Landguard Fort. Its armament consisted of two twin Q.F. 6 pdrs. Immediately behind each equipment was a Director Tower, which contained the Search Light Directing station, Director No.13 Mk. I and Officers Watch Shelter.  The primary role of the Battery was anti-motor torpedo boats and anti- surface submarines.


The Battery was constructed at about the same time as Landguard Right Hand Battery (1898-1900). It was originally armed with two 4.7” Q.F. guns and was manned during the Great War and also during the Precautionary Period (Sept 1938). On the outbreak of War, it was manned by detachments of 166 Heavy Battery R.A.(T.A).  Two 12 pdr guns were emplaced in Jan 1940 to augment the 4.7” equipments. During April 1940, the two 4.7” guns were reduced and dispatched to Norway but were sunk in transit.  Work on reconstruction and rearming of the Battery was commenced during May 1940. The 6 pdr equipments were in place and calibrated by early July and the two Director Towers completed during the winter of 1940/41. The two 12 pdr guns were reduced and dispatched to Iceland during June 1940.


The Battery faced a westerly direction.  The guns were situated 60 feet apart with Director Tower 13 feet behind each gun.  Number two tower contained the Section Observation Post on the top floor, with the S.L. Directing Station below. The room below the Directing Station was used as telephonist’s room and below that was the Officers Shelter. Number one tower contained the Gun Observation Post and below that a reserve Directing Station.  Below the Directing Station was a telephonist’s room and the Officers Shelter.  A reserve Watch Shelter was to the rear of and below number two tower. The magazines were situated to the rear and left of Nos.1 and 2 guns respectively   and were provided with power hoists.

Five CASL’s were allotted to the battery and were situated on the foreshore, three to the right flank, one immediately in front of the Battery and one on the left flank.

During the day, the Battery was not to open fire without orders from Fire Command except against obviously hostile vessels or against un-notified submarines or motor torpedo boats not flying the “Ship to Shore” letter.


During night or conditions of bad visibility, the Battery was to open fire on any vessel on which the Section Commander had received no previous information on unless the vessel was flying the “Ship to Shore” letter. If in doubt, a “Bring to” round was to be fired.


The Battery was not to take part in the barrage scheme or to participate in “Radar Concentrations”.


The Battery was allocated a secondary anti-aircraft role with the required modifications needed authorised in March 1945 but not completed until 1948.
