Title: Nazi Hollow Charge Attack on Belgian Casemate
Subject: German airborne troops using hollow charge explosive ordnance in their attack on a Belgian Fortress during the Blitzkrieg.
Investigation made at: Fort Eben Ema雔, Municipality of Eben Ema雔, Belgium
Period Covered: May 10th & 11th, 1940
Date: April-May 2010
Case Classification: Case Closed
Introduction: This Case File (#14) describes a small element of the assault on the Belgian fortress Eben Ema雔 in May 1940. Scores of publications have been written about this fortress and the overall assault on it, but we focus on a special weapon first put to use for military assault purposes.
REASON FOR INVESTIGATION: In the period right after the attack and during the Nazi occupation of Belgium and other European countries, the German propaganda machine did exploit their successful raid on the fort, but deliberately failed to mention the use of "new types of assault weapons". At Eben Ema雔 the assault glider and the hollow explosive charge got their baptism of fire. In this Case File we reveal to the general public the use of the hollow charge as a weapon kept secret to it by the Nazi's.
SYNOPSIS:
The Belgian fortress was constructed inside a hill with artillery casemates and armored cupolas on the hill's plateau and was considered impenetrable at the time it was built, between World War 1 and 2. On May 10th 1940 it was proven that the concept of national defense by means of gigantic chains of fortified artillery positions had become obsolete. On that day well-trained German airborne assault troops used speed, the element of surprise and new military techniques to put the fortress's powerful artillery out of action in a very short amount of time. One of the aforementioned new military techniques was the assault glider; the other special weapon was the so-called hollow charge.
A hollow, or shaped, charge is a concave metal hemisphere or cone (known as a liner) backed by a high explosive, all in a steel or aluminum casing. When the high explosive is detonated, the metal liner is compressed and squeezed forward, forming a jet whose tip may travel as fast as 10 kilometers per second.
Charles Edward Munroe was the inventor of "The Monroe Effect" in explosives in 1885. He noted that a high explosive with a cavity facing a target left an indentation. The Monroe Effect was rediscovered by Von Neumann in 1911, but no practical applications were developed. A Monroe-effect shaped-charge warhead can be expected to penetrate armor equal to 150-250% of the warhead.
