Colonel Klaus Wolf's military career in the Bundeswehr has taken him to Turkey on two postings. In the first of these, between 2002 and 2006, he took advantage of his contacts and access to research material to examine the military cooperation between Turkish and German forces during the lead up to the war and then, in particular, at Gallipoli 1915. This book (originally published in German in 2008 and in Turkish in 2015) is the outcome of that work.
