Boulogne; At 10:00 batteries Creche 1 and 2 were heavily bombed, a lot of materialloss. Wimereux (just North of the coastalfortress Boulogne) was lost for the Germans after heavy streetfighting. The commander of Marine Artillerie Abteilung 240 fought its way to Cap Griz Nez with 250 of his men.

on 22.9.44 the OKM Seekriegsleitung anounces at the Lagebesprechung the start of the radiobroadcasts with the surrounded fortresses in France. One of the tasks was to pass important messages from familiy to the German soldiers in the fortesses (for instance Lorient, St-Nazaire and Dunkirk).

Because of the fast deteriorating front-situation the heavy coastal Marinebatteries of "Todt" (4x38cm) and "Lindemann" (3x40,6cm) in the Pas de Calais got the order to empty the ammo stores and fire at Englisch cities on the southcoast, starting 1 September 1944.

Jack Koorneef @bunkerkruiper.bsky.social · 31/08/2026

To stop the Allied advance several of the coastalbatteries were taken from the coast and went to cover the retreat of the German troops (for instance the batteries 1., 3., 5. and 6./1245 from the area Etaples and 2./1244 near Dunkirk), others like 2., 8,. and 6./1245 moved to the Somme.

Today 82 years ago the Festung Le Havre was encircled by Allied troops, the destruction and blocking of the harbour is ongoing but slow due to the bad weather.

On 31-8-1944 the demolishing of the Dieppe and Fecamp harbours was declared finished. The harbour and facilities were out of order for a long time (according to the OKM). It seems that also the harbour of Le Treport had to be demolished but there was no contact with Le Treport.

Two weeks ago we had a nice day visiting the Bikers Festival at Spa-Francorchamps. Beautifull bikes, great people and a good sporty atmosphere. We will be back next year (maybe for the weekend, this year only Friday and Saturday, due to the biggest fire in Belgian history sunday was cancelled).

Only one week left before we will revisit the battery of Bihen.

Jack Koorneef @bunkerkruiper.bsky.social · 27/08/2026

Furthermore the Hospitalship "Oakland" was that heavily damaged that it can not be moved elsewhere. Accordance was given by the Fortresscommander to destroy the harbour on 28-8-'44 starting with the commercial-harbour and parts of the shipyard workshops.

This island Cézembre in the bay of St-Malo is only 700 by 300 metres and was already fortified by Vauban (as many of the small islands in the bay) The Germans places a coastal battery with 6x 19.4cm on it. Now it is a nice island with lots of birds and in the summer a nice covered beach.

Jack Koorneef @bunkerkruiper.bsky.social · 27/08/2026

27-8-1944; At St-Malo the Island of Cécembre is still under fire. on 25-8-1944 300 shots were fired and at 15:00 an airbombardment took place and 200 bombs fell. No guns were damaged and no loss of human life. On 26-8-1944 the battery was shot at by former German guns from Battr. Grand Bey.

OTD Near (North-West) Lorient the Germans left resistancepoint Concarneau with all weapons and materials. The harbour was destroyed and harbourfacilities rendered useless by explosives. Concarneau was protected by several bunkercomplexes, the most important one on Pointe de Cabellou.

For instance Battery Spee and Camaret were engaged in the fire battles. On the other hand Battery Pree was itself also target of bombardments on 25-8-44 from sea, the enemy ships could not be attacked because of the bad weather. Radar personell from various locations in Brittany arriving in Brest.

The WSBK weekend was nice as usual. The Superbike races itself were a bit boring with Bulega winning everything but Supersport, Sportsbike and Northern talentcup were awome to watch.

Here some pictures of a nice Westwallbunker type 105b. It lies on a ridge south of Beckingen. The 6cm strong armored plate was hit by a 5.7 or 7.5cm armor piercing grenade. The light green color inside the bunker is original WW2.

Jack Koorneef @bunkerkruiper.bsky.social · 17/01/2026

Found a new message: Tagesmeldung of 16-6-1944 in the KTB of AOK 15; During the bomberattack on the 14th the Kriegsmarine had 72 dead, 245 wounded and 55 missing. The airforce had 3 dead and 2 missing.

Measures were to be taken to prevent the crossing of the river by the German soldiers, S.D. would get the full cooperation from the Feldgendarmerie. Not only Germans tried to flee the German occupied part of The Netherlands but also Allied Airman (and Para's that fought at Arnhem) and civilians.

010

Jack Koorneef @bunkerkruiper.bsky.social · 23/12/2025

The S.D. and Feldgendarmerie came back three days later, this time a Kriegsmarine-Officer was arreste, another 20 persons were also taken away. 4 more avoided this same fate. A conversation between a waiter and an S.D. agent was overheard and the S.D. was planning a more solid investigation.

Jack Koorneef @bunkerkruiper.bsky.social · 23/12/2025

OTD The S.D. was ordered to Gorinchem to investigate Germans that wanted to cross Boven-Merwede river to surrender, one of them, a German Officer, had new information on the V-weapons for him it did not work out even with help from four other men that wanted to do the same, and he left.

Some pictures of the airbornelandings at Ginkelseheide, Ede, Netherlands. Para's from England, Greece, Germany, France, the Netherlands, America and other nations jump here not only to reenact the 1944 airbornlandings but also to practise in the phantomleap operation.

16:40 Ob.West orders the Pz.Brig.107 (which is on the move to the battlefield) to the direction of Bocholt. (Pz.Brig.107 will play a crucial role in cutting off "Hell's Highway" later on in the battles and preventing fighting units and supplies reaching Arnhem.)

Jack Koorneef @bunkerkruiper.bsky.social · 18/09/2025

16.40 part two; To reenforce these units, Ob.West orders to instantly alarm units of SS-Pz.Div. (troops that need refreshing) in W.Kreis.VI to be used as Kampfgruppen. Ob.West orders 50.000 men ("Blücher and Gneisenau" in W.Kreis VI) are to be used to secure the bridges over the Rhine.

16.35 Message of Gen.Kdo.VI to Ob.West; Our earlier view on the situation: Focus of enemy landings river Maas and the Maas bridges and not the river Rijn.

Jack Koorneef @bunkerkruiper.bsky.social · 18/09/2025

16.40 OKW informs Ob.West (with info from W.B.N.) about the landings and the German counteractions (especially about the parts of II.SS.Pz.Korps in the area of Deventer, Sich. Btle. and other ad hoc units. More messages from Verb.Kdo.Lw.; Focus of the landings at Arnhem, alleged landing at Xanten.

Jack Koorneef @bunkerkruiper.bsky.social · 18/09/2025

15.50 Ob.West informs all units (of all branches of the Wehrmacht) about the landings and reports to OKW (Ober Kommando Wehrmacht).

Jack Koorneef @bunkerkruiper.bsky.social · 18/09/2025

15.15 Inquiry Ob.West to Gen.Kdo.Feldt (HQ Hüls near Krefeld), defensive actions against the enemy landings. All available units of the 406 Inf.Div. attacking in the area Kleve-Kranenburg and Goch. Acting commander of Gen.Kdo.IV same actions but in area Wesel, 1 Batl. ordered to Arnhem.

I was not driving, but we had a good driver/captain. The clip i made was too long.

Jack Koorneef @bunkerkruiper.bsky.social · 29/08/2025

It is a bit strange that it was dug there, the Pantherstellung follows more or less the 1939-1940 defenceline of the Grebbelinie/Valleistelling. This line already had a Antitank ditch so why dig another? That the Grebbelinie lacked dept is probably the reason but also a guess.

010

Jack Koorneef @bunkerkruiper.bsky.social · 29/08/2025

Last Wednesday i went to search for the last remaining part of the antitank ditch of the Panterstellung in the Netherlands. Well not really searching but visiting. Most parts were re-cultivated and are now filled. But in a small Forrest a short stretch was left.

9 At the end the plans for the dome were chosen and not the miningplans. Bombardments as expected ended the project and now a museum is located under the dome about the Rocketplans in and after WW2. Never visited the museum but once stood on the impressive concrete dome.

010

Jack Koorneef @bunkerkruiper.bsky.social · 28/08/2025

8 Another option was to lift the roof of the old Watten bunker with hydraulic presses and move on with the project, but new bombardments could demolish the presses and bombs falling on previously hit parts would penetrate and destroy the bunker. The hit parts were to get a 5m extra layer of concrete
