On 2nd September I drove out to Southease (between Newhaven and Lewes) to take a look at seven roadblock locations.

There was quite a bit of activity in the area during the war, as the village is near the River Ouse, which formed part of the GHQ Line.

Prior to this trip I had researched the roadblocks, but not the GHQ Line aspect, so it was a pleasurable experience to come across a couple of Type 24 pillboxes unexpectedly. Although they had already been recorded by the Defence of Britain Project, I'd forgotten that particular feeling you get when you make a connection between defence works whilst actually out in the field; making the same connection at the desktop is not always so exciting.

Roadblock recce

I discovered the first of these pillboxes at Southease crossroads, which is a staggered junction; the image below shows its location along with that of a pair of buoys dug into the roadside. Both have been decapitated down to ground level, perhaps by being struck by vehicles, or by the sledgehammers of those who regarded their presence as a nuisance.

Roadblock recce

Moving down the road to another roadblock location, I came across the second pillbox at a junction with a side road.

The block on the main road consisted of 18 cylinders and 6 pimples and was described in the Roadblock Report as "USELESS", while another block was proposed for the side road. There is no surviving evidence at either location.

The Canadians built a Hamilton Bridge over the Ouse in 1941; at this time, I'm not sure if this replaced an existing bridge, as the DoB records a Type 28 pillbox in the area. The Canadian documents make no mention of building it, so I can only assume that it dates to 1940 and protected an earlier bridge. I also assume that the bridge is that which survives to this day.

Southease Bridge

Whatever the case, the Canadian bridge increased the importance of Southease, and documents show that the roads were by 1942 covered by no less than six barrel flame traps (flame fougasses). A cursory glance at the stated roadside locations revealed nothing; a return trip once the vegetation has died down might prove interesting.

Barrel flame trap

Incendiary booby-trap comprising a battery of oil drums dug in and concealed, usually in a roadside bank and detonated remotely as an enemy vehicle passes it. Also known as a flame fougasse.


Small concrete roadblock obstacle comprising a truncated cone with domed base. A hollow shaft down the centre allowed the buoy to be manhandled using a crowbar. Buoys were deemed of little value by 1941 and cylinders seen as a better solution.


Reinforced concrete cylindrical obstacles with a shaft down the centre in which could be inserted a crowbar for manhandling, or a picket for barbed wire. Cylinders were 90cm high and 60cm wide and deployed in groups of three as a more effective alternative for buoys.

Defence of Britain Project

A large project run by the Council for British Archaeology (CBA) 1995-2002, collecting data on 20th century military structures submitted by a team of some 600 volunteers. The result was a database of nearly 20,000 records which is available online. The anti-invasion section of the database contains nearly 500 entries for East Sussex.

GHQ Line

A series of arterial stop lines designed to prevent German forces advancing on London and the industrial Midlands.


Generic term for a hardened field defensive structure usually constructed from concrete and/or masonry. Pillboxes were built in numerous types and variants depending on location and role.


Small anti-tank block in the form of a truncated pyramid. Pimples were used to extend anti-tank obstacles and roadblocks and were intended for use on soft ground.

Type 24 pillbox

A six-sided (but not a regular hexagon) pillbox. The Type 24 is the most frequently seen pillbox in East Sussex, mostly along stop lines. It can be found in thin wall (30cm) or thick wall (1m) variants.

Type 28 pillbox

A pillbox designed to house a small artillery piece (typically a WW1 6-pounder gun), usually sited to cover a bridge or other defile. Type 28a variant had an additional compartment for infantry defence.
