Information

17cm K18 gun.

Details

As you can see a very heavy gun, it can be fired on a turntable or on its carriage (Lafette). It took a large crew and needed a heavy towing tractor to pull it. The only problem was the time to assemble and disassembled, it took too long and many were left behind as the Germans retreated through France.

Information

R688 gun room.

Details

The 17cm K18 gun was based on the 22cm carriage and it turned out to be a better gun with a long range and the ability to fire like a mortar, almost vertically. That is why this casemate was designed to allow the gun to fire 120deg. left to right and almost vertically.

Look at the massive steels used in the roof structure alone, it must have been a most costly bunker to produce.

Information

R688 rear door.

Details

This should have been fitted with a heavy steel door that was either removed after the war and scrapped or was actually never fitted and may have been sat in a railway siding somewhere in France due to the disruption of the rail network by allied air forces.

R688 Turm3

Details

Now this is Turm 2 and as usual so camouflaged by undergrowth and at the back the towns rubbish heap.
We did not realise Turm1 may still be there somewhere, I have seen pictures on the Internet in fact I have seen pictures of all four so maybe the crater was an ammunition magazine blown up???
