Michael Cassidy, sergeant (1915) on Internet Archive at http://www.archive.org/details/michaelcassidys01mcnegoogWikipedia wrote:His first known published works were a series of short war stories based on his own experiences, published under the name Sapper in the Daily Mail and in The War Illustrated.
These stories were immediately successful and later sold over 200,000 copies within a year when republished in book form. His writing caught the public mood at the time - it was grimly realistic enough to seem authentic, yet managed to conceal the horrific reality of trench warfare and life at the front line.
