The Brown Brethren explores the story of men who lived and died in the trenches during World War One. Any English soldier wearing brown had become one's “Brown Brethren” during the War in the channels. This is a thrilling as well as a painful tale that will leave a person thinking about it long after it is finished. The Irish author and journalist Patrick MacGill served during the First World War with the London Irish Rifles. This service led him to describe the events in this book more honestly and with such strong emotions.
