According to the Metro:
Capt Robert Campbell wrote to Kaiser Willhelm II during World War I begging to be released so he could see his mother, Louise, for the final time.
The German leader granted him two weeks’ compassionate leave as long as he kept his word as an officer to go back to the camp afterwards – which he did.
Capt Campbell returned to the camp in Magdeburg and stayed until the Armistice two years later. He served during World War II and died in 1966 at the age of 81.
