Most powerful and modern of the forts of Liége, Eben-Eymael covered more than 200 acres and had an armament of two 12-centimetre guns (about 4.7-in.), over 30 of 6.5 and 7.5 cm., besides a large number of machine-guns, etc. Of its impregnability Belgium's military experts were convinced, and yet only a few hours sufficed for its capture by the Nazis. At first it was said that their parachutists descended on the cupola and threw hand grenades into the interior, but these photographs, reproduced from the German publication "Die Wehrmacht", prove rather that it was the severity of the aerial bombardment, combined with the mines laid by the parachutists, which broke the garrison's resistance, thus enabling picked storm troops to take the fort by assault. A Belgian soldier wounded in the defence of the fort confirmed the main outlines of the story.

The fort is obviously misspelled here, it Fort Eben-Emael. Unfortunately we were not able to reproduce the pictures with this article.
