Antwerp -x- medal
Together with the decision to place the memorial plaque on the Rubenslei, an investigation was also ordered into a commemorative medal "Ter Ere van Antwerp X".
The order for this went to art sculptor Arthur Dupon who had to design and deliver “The medals, the bronze casting of the model, as well as the molds that remain the property of the City” before the end of August 1945. From 9 July, approving articles appeared in the Antwerp press with an image of his plaster model.
The 55cm large plaque was presented to the moved Armstrong on September 4, 1945, the first anniversary of the liberation, however relative it may have turned out in retrospect.
Mayor Huysmans presented them to him in front of the City Hall, where he himself had just received the War Cross that had been awarded to Antwerp.
"Gene. Armstrong, greeted with an endless ovation, finds some short simple clear words to thank the “friends from Antwerp” for their sympathy.
“When we saw how brave you stood in the danger,” he says, “we felt proud to be working with you. Your determination has been an example to us.”

In addition to the large one, 50 medals of 9 cm were also made, 20 of which were presented to the commanders of Antwerp X.
All medals bore the text “Antverpia mutilata sed grata Brig. cl. H. Armstrong sociisque” and the 20 medals for soldiers were also provided with their name, degree and unit at the time of Antwerp X at the back. and they especially praised the attitude of the citizens.
“Compared to the men, women and children of Antwerp who, with such admirable courage and faith, endured the worst scourge that can strike a city, I am actually not worthy of the medal you sent me. But she will always occupy a place of high honor in my home, as she is a tribute to a very gallant people.”
Harold P. Hennessy, Chief of Staff Antwerp X, 2.2.1946.
