World War I
When the Germans got to the Belgian city of Liège, the Belgians fought very hard to stop them from coming into the city. The Germans finally pushed the Belgians out of the city, but it had taken longer than the German generals had planned. The Germans then attacked the north side of the French army. The French and the British moved men up to fight the Germans because the Belgians had fought so long at Liège. However, the Germans pushed the French back at the frontiers, and the British held the Germans back at Mons, but they also fell back to join up with the retreating French Army until they were stopped at the river Marne. This was the First Battle of the Marne or "Miracle of the Marne".
