James Norman Hall 
Kitchener’s Mob / Adventures of an American in the British Army [EPUB ebook] 

James Norman Hall (22 April 1887 – 5 July 1951) was an American author best known for the novel Mutiny on the Bounty with co-author Charles Nordhoff. During World War I, Hall had the distinction of serving in the militaries of three Western allies: Great Britain as an infantryman and then flying for France and later the United States. James Hall begins his story of Kitchener and the men who fought with him on the Western Front as follows. "Kitchener’s Mob" they were called in the early days of August 1914, when London hoardings were clamorous with the first calls for volunteers. The seasoned regulars of the first British expeditionary force said it patronisingly, the great British public hopefully, the world at large doubtfully. "Kitchener’s Mob, " when there was but a scant sixty thousand under arms with millions yet to come. "Kitchener’s Mob" it remains to-day, fighting in hundreds of thousands in France, Belgium, Africa, the Balkans. (Excerpt from Wikipedia and Goodreads)
