As part of the 11th SS Panzergrenadier Division "Nordland", and with the rank of Hauptsturmführer, Miguel Ezquerra fought to defend the town of Stettin on the Oder River.

[citation needed] From April-May 1945, Ezquerra was in Berlin leading three companies of Spanish volunteers defending the city from advancing Soviet troops.

Ezquerra had linked up with remnants of the Charlemagne Division and Volkssturm volunteers and fought in the central Reichstag district, being among the last defenders of the bunker of Adolf Hitler.

[3][4] He was briefly captured by Soviet troops but was released and after various misadventures across Western Europe, where he passed himself off as an Argentine citizen, Ezquerra returned to Spain.

Some historians, such as Kenneth W. Estes, question the assertions made by Ezquerra himself, as no evidence has ever been found to corroborate his claims about the role he played.

He claimed to have had personal contact with Hitler, who orally (of course) awarded him the Knight's Cross; Himmler, Goebbels, and Berger; and to have seen Martin Bormann and Axmann.
