What was a notable condition of the battlefield during the Battle of Passchendaele?

The Battle of Passchendaele, also known as the Third Battle of Ypres, is notorious for the atrocious weather conditions that characterized the battlefield. During the battle, which took place in late 1917, heavy rainfall transformed the landscape into a quagmire. The excessive mud made movement extremely difficult for soldiers, severely affecting their ability to carry out operations, maintain supply lines, and retreat if necessary. Not only did the muddy conditions hamper combat effectiveness, but they also contributed to a high number of casualties and issues with hygiene and health among the troops. The persistent wetness and mud became a defining feature of this engagement, making the choice of "Muddy and wet" the most accurate description of the battlefield conditions during the Battle of Passchendaele.
