The Siege of Antwerp, which lasted from late September to early October 1914, marked a significant military confrontation in World War I. Antwerp was of great strategic importance due to its status as a major port city in Belgium and as a logistic hub for the Allies. German forces, having made significant advances into Belgium, focused their efforts on capturing Antwerp to further destabilize the region and secure their supply lines.

During the siege, the Belgian Army, alongside British support, defended the city with determination. However, the German military employed advanced artillery, including big guns, which proved to be destructive and overwhelming. The siege featured intense urban fighting, and the defending forces were outmatched both in numbers and firepower. After weeks of fierce resistance, the Belgian garrison was forced to retreat, leading to the fall of the city on October 9.

The capture of Antwerp not only marked a victory for Germany but also facilitated their plans to advance deeper into Belgium and secure control over critical supply routes. The event had a notable effect on the morale of both the Allied and Central Powers, influencing military planning and operations in the ensuing months of the war.
