In May 1916, Anton Baumgartner sent a POW postcard to his son Otto in Novo Nikolayevsk POW camp in Siberia (now Novosibirsk). Otto Baumgartner is only one of hundreds of thousands of soldiers who fell into enemy hands during the First World War. One in thirteen German soldiers, one in ten French and Italian, one in five Russian and almost one in three Austro-Hungarian soldiers ended up in captivity.
