He took his heavy gun battery all the way to the banks of the Volga: Dr. Wigand Wüster, now a lawyer and then a 22-year-old battery commander. Shortly before the 6th Army was trapped by the Russians in Stalingrad, he went on leave. He then had himself flown in to join his troops. So he fought until the last day in 1943, the bitter end of the 6th Army. After that, he went into long-term captivity in Russia. He wrote down his experiences in a book. With self-painted pictures.
