Pillbox Types

7 posts

During May 1940 the branch of the Directorate of Fortifications and Works (FW3) at the War Office was set up under the Directorship of Major-General G.B.O. Taylor. It’s purpose was to provide specific pillbox designs to be constructed throughout the countryside at defensive locations.

During June and July 1940 saw the FW3 branch issue 7 Basic Designs. However, often, once in the field, the local construction companies modified these under the direction of the area commands. Occasionally, a ‘one-off’ type was designed to the War Office standard by the Command and Corps Chief Engineers.

This then is the fundamental basis for the thousands of pillboxes that we find littered across our present day landscape.

The FW3 pillbox design concept was to provide a simple ‘fieldwork standard’ that could be constructed very quickly. Most designs consisted of or incorporated some of the following features:

Minimum of Bullet/Splinter Proof protection
No attempt was made to provide living accommodation
Some designs were enhanced to Shell Proof standard
Simple Blast Walls to protect open entrances
External flat side walls with rectangular or polygonal shape
The use of common designs with standard sizes for doors, loopholes and flat sides made it easier to `mass produce` items for concrete shuttering and hence the speed of construction. However, with the general countrywide lack of material it was often necessary to use bricks as the shuttering. This often fools the casual observer into believing that the whole structure is constructed of brick. Closer examination often reveals the integral reinforced concrete ‘back-bone’!

Type 22 Pillbox

Key Facts One of the areas for most variation will be found in the shape of the Loopholes and the internal provision of weapon rests.   There appears to be no hard and fast rules but the norm for the Type 22 Pillbox, essentially designed for use by riflemen, is […]

Type 24 Pillbox

Key facts Information obtained from pillbox typology part 2 in Loopholes journal of the PSG. With kind permission of Mike Osborne. FW3/24 Shellproof This type can be found along the route of GHQ Line A in Hampshire and Line B in Surrey with all walls built to a thickness of 51″, examples […]

Type 26 Pillbox

Key facts This is probably the simplest of all but not the most common pillbox type. Variations in the standard design have been identified in Dorset, Kent and Somerset. The ‘Dover quad’ is a 13ft (4m) square pillbox with an overhanging roof slab. The ‘defence post’ found in Somerset is a little over 8ft (2.4m) square with […]

Type 28 Pillbox

Key Facts FW3/28 Generally, the pillboxes are positioned to allow the gun to fire along fixed lines, such as enfilading fire across an anti-tank ditch or a bridge. In these positions the limited traverse of the gun creates no real disadvantage and the small size of the embrasure provides greater […]
