Recruitment to the British Army during World War I was carried out initially by seeking volunteers: 100,000 were called up in early August, and within two months, almost half a million men had enlisted. This 1914 recruitment poster by the Parliamentary Recruitment Committee shows a Scottish soldier in Belgium, in response to German chancellor Theobald von Bethmann Hollweg having described the Treaty of London (which protected Belgium's independence and neutrality) as a "scrap of paper" when Germany invaded Belgium in August 1914.Poster credit: Lawson Wood; restored by Adam Cuerden
