Battle of Liège
Summary
The Battle of Liège opened the First World War on the Western Front. The forts encircling the city resisted German attack for more than 10 days. French elements supported the Belgians on the Meuse and conducted offensive reconnaissance without changing the fate of the fortress. German heavy artillery decided the outcome.
Historical context
Germany violated Belgian neutrality and attempted rapid passage toward France. Liège resistance slowed the German advance and delayed entry of French and British troops into the Battle of the Frontiers.
Tactics
Fort defense, cavalry sorties, covering maneuvers by the French wing. German attacks concentrated heavy artillery on each fort until its destruction.
Consequences
The fall of Liège heralded rapid invasion of Belgium and prepared the Battle of the Frontiers. It gave the French army time to deploy Plan XVII and the British to land in France.
