are mentioned on two occasions in the Order of the Day of the Belgian Army and granted the Fourragere 1940 for:
1. The units of Antwerp X Command played a heroic role in establishing and maintaining the antiaircraft defense for the liberation of the port of Antwerp which permitted the opening of the port on November 28, 1944, by defeating the all-out attack of the German V-1 bombs launched from the Trier area, as well as from the area North East of Nijmegen. The destruction of property and loss of life of both Belgian civilians and Allied troops was held to an absolute minimum through the tireless efforts on the part of the members of these units. Fighting day and night, the soldiers accomplished their mission in an outstanding manner which had as result the liberation of the Port of Antwerp and permitted the flow of supplies and munitions* to the five Allied armies. The heroic action of the members of these units reflects the highest credit upon the Antwerp X Command and the Allied armed forces.
2. The units of the Antwerp X Command, at the time of the all-out offensive launched by the Wehrmacht [German army] on December 16, 1944 [Battle of the Bulge], established an unprecedented antiaircraft defense against the attempts to destroy the port of Antwerp. The results of this heroic action, the success of which was absolutely vital to the Allied cause in general, and in particular, the preservation of the liberation of Belgium, were so successful that the operation of the port was never interrupted.
The courage of the officers and men, combined with their tireless efforts and technical skill, closed the campaign with the unprecedented gunnery score of 97 per cent.
*Actually, the only ammunition coming through Antwerp was that used by the anti aircraft batteries. All other explosives were run through Cherbourg and Le Havre to keep them safe from V-weapons.
