The digging lasted through 1942 and 1943, when it was stopped after the Allied bombing of Belgrade began. By 1943, the Germans completely rebuilt the Gate of Charles VI, in greatest detail. Reconstruction included the cartouche with the initials of the emperor on the capital from the outer side, and the supposed coat-of-arms of never-existing Tribalia, on the inner side (boar with an arrow pierced through the head). As the motive of this coat-of-arms appeared in medieval Serbian seals and was adopted as part of the Serbian coat-of-arms after First Serbian Uprising in 1804, it was meant to show the incorporation of Serbia into the western empire. The gate was damaged already during the heavy Allied Easter bombing in April 1944.
