The Guns of August describes how the crisis erupted quickly and almost no one grasped the full picture.

True: Barbara Tuchman's The Guns of August is shown to centre on how the 1914 crisis and the outbreak of the First World War unfolded quickly, and on how decision-makers lacked a full understanding of the situation (misperception, miscalculation). Mostly true: the book covers both themes, but one is a secondary rather than the main theme. Mixed: the book covers only one of the two elements in a substantial way. Mostly false: the description misstates the book's focus, for example its main subject is the opening military campaigns rather than the crisis, with only incidental support for the claim. False: the book does not deal with these themes.

   “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.”

2. E2 The Guns of August - Wikipedia Wikipedia · 2 June 2004

   “The nations were caught in a trap, a trap made during the first thirty days out of battles that failed to be decisive, a trap from which there was, and has been, no exit.”

   “It relied on attacking France through Belgium with a strong right wing, but Schlieffen's successor as the chief of German General Staff, Helmuth von Moltke the Younger, weakened the plan, leading to assumptions of a swift victory that were overly optimistic (chapter 2).”

4. E4 The Guns of August - Wikipedia Wikipedia · 2 June 2004

   “McNamara related that Kennedy said The Guns of August graphically portrayed how Europe's leaders had bungled into the debacle of World War I, and that Kennedy later told his cabinet officials that "We are not going to bungle into war."”

E1 describes the book as a narrative of the war's earliest stages, from the decisions to go to war until the start of the Franco-British offensive that stopped the German advance into France. E2's 'first thirty days' passage supports the claim that events unfolded fast. E3 and E4 show that misperception and miscalculation are substantial themes: overly optimistic assumptions of a swift victory, and Kennedy's reading of the book as showing that Europe's leaders 'bungled' into war. Both elements of the claim are present; the book's scope runs from the decisions to go to war until the start of the Franco-British offensive [E1], so the crisis is one part of a broader narrative that also covers the opening campaigns.
