The Guns of August (published in the UK as August 1914) is a 1962 book centered on the first month of World War I written by Barbara W. Tuchman. After introductory chapters, Tuchman describes in great detail the opening events of the conflict. The book's focus then becomes a military history of the contestants, chiefly the great powers.
The Guns of August provides a narrative of the earliest stages of World War I, from the decisions to go to war up until the start of the Franco-British offensive that stopped the German advance into France. This led to four years of trench warfare.
