This is a small part of the story of the indicator loop station built during WW2 as part of the Royal Navy's anti-submarine harbour defences of The Schelde River, Netherlands. It is located between Walcheren Island and Nieuwe Sluis, 3 km west of the village of Breskens. Six Indicator Loops were laid in 1945 to detect German U-Boats. After the war the number of loops were increased to twelve.

With the surrender of the German garrison
on Walcheren Island, early November 1944, the operations to clear the Germans
from the riverbanks of the Scheldt were completed. Minesweeping commenced
but it was not until the end of the month that the first allied supply convoy
eneterd the port of Antwerp. The Germans understood the importance of Antwerp
and ordered their navy and airforce to bring the Thames-Scheldt convoy route to
a standstill. The German Navy made use of E-boats, the midget submarines
Biber, Molch and Seehund and a small surface vessel Linsen.
The Luftwaffe operated with Junker 88 aircraft to lay mines in the convoy
channel. The battle dragged on until the end of the war.
To counter this threat, RAF 85 Group, 2nd Tactical Airforce set up mobile radar
stations along the Belgian coast and on flooded Walchered. The Royal Navy
patrolled the river mouth with ASDIC (sonar) and depth charged where necessary.
On the seabed between Flushing and Breskens high lighthouse (pictured below),
six anti-submarine indicator loops were laid to detect passing underwater craft.
