The website Christmas Truce 1914: Operation Plum Puddings has been created by Alan Cleaver and Lesley Park. They aim at bringing together letters of soldiers, songs and other materials concerning the spontaneous truce of Christmas 1914. In particular activities such as singing and football games get attention. The website presents many letters written by British soldiers from several regiments. There is a provisional list of British and German Christmas songs. People are invited to do research in newspapers with reports about the Christmas truce, and to bring relevant letters and notices to the attention of the creators.
