The real action now is in Flanders. Belgian forces are defending the Yser river, holding desperately onto a tiny corner of their homeland. The Germans begin to assault the line. Falkenhayn hopes to destroy the Belgian army and then roll along the coast to the French Channel ports.
Around Ypres, a British and French force is pushing east. There seems to be a gap between the German armies to the north and south, a gap the Allies hope to exploit.
