The failure of either side to achieve a breakthrough around Ypres effectively marked the end of any real chance for the Allies or the Germans to outflank each other before running out of room to maneuver. The remaining strip of territory was a narrow coastal belt along the North Sea in westernmost Belgium, prone to flooding and thus not very passable. By October 19, the Belgian army, completing its westward withdrawal from Antwerp, had reached this ground and began to entrench, its flanks resting on the North Sea to its left and the BEF line to its right. This brought the "Race to the Sea" to an end. | The failure of either side to achieve a breakthrough around Ypres effectively marked the end of any real chance for the Allies or the Germans to outflank each other before running out of room to maneuver.
