What Led to the ‘Race to the Sea’ in World War I?

When World War I began, Germany attempted to carry out its plan of attack, which was referred to as the Schlieffen PlanGermany’s military strategy to quickly invade France through Belgium to avoid fighting two enemies at once..  In short, the Schlieffen Plan was Germany’s response to being surrounded by the Allied Powers.  For example, on its western border, Germany had to contend with France and Britain, while on the eastern border they had to face the Russian Army.  In response, Germany developed the Schlieffen Plan, which aimed at advancing quickly through Belgium and attacking France.  The goal of the Schlieffen Plan was to capture Paris, the French capital, and knock France out of the war, thus eliminating a two-front war.

Q

How did Belgian soldiers stop the German advance near the North Sea in October 1914?

A

In late October 1914, Belgian troops opened the sluice gates at Nieuwpoort and let seawater flood the low land along the Yser River. The flooding created a wide barrier of water that the German army could not cross, and this stretch of the front stayed flooded for the rest of the war.

Stalemate Locked InNeither German nor Allied forces could outflank the other as they moved north, so both sides dug defensive trenches to hold their positions. This deadlock ended the fast-moving battles of the war's opening weeks.
Trenches Stretched Across Belgium and FranceBy late October 1914, a continuous line of trenches ran from the North Sea coast through Belgium and into northeastern France. This line became the Western Front, where fighting continued for the next four years.
The Schlieffen Plan Failed for GoodGermany's goal of quickly capturing Paris and knocking France out of the war was finished once the trench line formed. The two-front war Germany had tried to avoid became a reality.
Years of Trench Warfare FollowedThe fixed trench line meant that neither side could advance without enormous cost in lives. Major battles like the Somme and Verdun were fought along this same line in the years that followed.
