According to Churchill why was that battle of France lost

Answer:- Winston Churchill claimed that a number of events contributed to the Battle of France’s defeat, including:

• In order to breach opposing defenses and encircle their forces, the Germans used the blitzkrieg, a novel style of warfare.
• The French army, which was still using antiquated tactics and weaponry, was not ready.
• The inadequate performance of the French high command, which committed numerous serious errors, including failing to timely evacuate the French army from Belgium.
• The British Expeditionary Force’s (BEF) inability to support the French army effectively.
