Which dates correspond to the Battle of Passchendaele?

The Battle of Passchendaele is specifically known for its duration from October to November 1917, making it an important phase of World War I characterized by brutal trench warfare and extreme conditions, particularly the mud that plagued the battlefield. Although the battle preparations and related military actions might have occurred earlier in 1917, the primary and most significant fighting took place during the defined months of October and November.

The choice indicating that the battle occurred from July to September presents an inaccurate timeframe, as that does not align with the actual events. Similarly, while there might have been preliminary maneuvers or strategies developing earlier in the year, this option does not capture the main combat period. Dates extending from March to August also misrepresent the timing, as they encompass a broader range than what is historically recognized for the Passchendaele offensive. Thus, the correct option is focused specifically on the final two months of 1917, which is when the key combat took place.
