 As its forces reached Nuremberg on 16 April, the Seventh Army ran into the same type of anti-aircraft gun defense that the 1st Army was facing at Leipzig.Only on 20 April, after breaching the ring of anti-aircraft guns and fighting house-to-house for the city, did its forces take Nuremberg.Following the capture of Nuremberg, the 7th Army discovered little resistance as the XXI Corps′ 12th Armored Division dashed to the Danube, crossing it on 22 April, followed several days later by the rest of the corps and the XV Corps as well.
