Capt Robert Campbell, of the 1st Battalion East Surrey Regiment, had been captured in northern France on 24 August 1914 and was sent to a POW camp in Magdeburg, north-east Germany.
While in the camp he received news that his mother Louise was dying of cancer. Capt Campbell wrote a letter to the German emperor begging to be allowed to go and see his mother, which the Kaiser allowed - as long as Capt Campbell gave his word that he would return.
Campbell travelled through the Netherlands and then by boat and train to Gravesend in Kent, where he spent a week with his mother.
Having felt a duty to honour his word, Campbell actually returned to the camp.
Upon returning, he then set about trying to escape. He and a group of other prisoners spent nine months digging their way out of the camp before being captured on the Dutch border and sent back.
He remained a prisoner until the end of the war, serving well into WW2.
