Final answer:
Without the specific source text, it is challenging to provide the exact positive attributes of Dresden as shared by an Englishman with American POWs. Typically, Dresden was known for its cultural heritage, beautiful architecture, and fine china before its destruction in 1945.
Step-by-step explanation:
The question seems to be in reference to an account of an English individual interacting with American POWs, likely during World War II, but the source text that would discuss the positive attributes of Dresden as shared by the Englishman with American POWs is missing. As such, it is not possible to accurately provide the desirable attributes of Dresden according to the Englishman's account without speculation.
Nonetheless, historically speaking, Dresden before its bombing in February 1945 was known for its artistic and architectural heritage, sometimes referred to as "Florence on the Elbe" due to its impressive Baroque and Rococo city center. It was also a center of cultural significance with numerous museums, the famous Semperoper opera house, and its reputation for fine china production at the Meissen porcelain factory, which could be aspects appreciated by visitors and shared between POWs and their captors.
