News: “Over the graves of the Druids and under the wreck of Rome,
Rudely but surely they bedded the plinth of the days to come.
Behind the feet of the Legions and before the Norseman’s ire
Rudely but greatly begat they the framing of State and Shire
Rudely but deeply they laboured, and their labour stand till now.
If we trace on ancient headlands the twist of their eight-ox plough.”

-Rudyard Kipling

I'm sure there are remains of one on the left just past the tunnel on the Maidstone Road in Chatham.

Another idea from the petroleum group was to set the Sea on Fire, again this system was tried out at Dumpton Gap Broadstairs and at other places the system worked but only really in calm seas. A bit of a problem in the English Chanel. The system went into use, the first proposal was for fifty miles of coast to be protected, this was reduced to thirty miles, then fifteen miles and finally to less than ten.
Completed sections were between Kingsdown and Deal, this section suffered damage during a winter storm. A further section at Sandwich Bay, the pump house was in the grounds of the Guilford Hotel. There was also a section at Shakespeare Cliffs, the tanks for this system were found when the A20 over the Western Heights was built back in the 1980s.

Beside the pillbox on Dover's Old Charlton Road (near The Danes Rec.) was a variation of this system. I have a vague memory of a large metal drum sunk into the bank. A stop line came down the hill nearby and restarted on the other side of the road. We've had discussions about these elsewhere on the Forum.

Many years ago I worked with men who were in the R.E. TA battalion formed at APCM Bevan's works Northfleet. I was told that they converted the handrails at several seaside towns so that petrol could be piped onto the beaches and slipways. This could be lit by a flare or small explosive change. They also put drums full in the sea shallows detonated by explosive. They set one off while a German plane flew over one day.

For the benefit of folk that that think fougasse refers to french bread. I pinched this snippet from Wick .
Quote :-
"In Britain, during WWII, the flame fougasse was usually constructed from a 40-gallon drum dug into the roadside and camouflaged. It would be placed at a location such as a corner, steep incline or roadblock where vehicles would be obliged to slow down. Ammonal provided the propellant charge which, when triggered, caused the weapon to shoot a flame 10 feet (3.0 m) wide and 30 yards (27 m) long. Initially a mixture of 40% petrol and 60% gas oil was used; this was later replaced by an adhesive gel of tar, lime and petrol known as 5B"

During ww2, anti-invasion defences came in many different forms. The Petroleum warfare systems group came up with many different ideas. Dumpton gap at Broadstairs was the site for many of the trials.
