Final answer:
The Phony War was a period of time after France and Britain declared war on Germany in 1939, during which no major military conflicts took place. Both countries were prepared for war but didn't engage in direct combat during this time.
Step-by-step explanation:
The Phony War refers to the time period after France and Great Britain declared war on Germany following the invasion of Poland in September 1939. During this period, no direct military conflicts took place between the countries involved, leading to its label as the 'Phony War.' Both France and Britain were prepared for war and had soldiers stationed behind the Maginot Line, anticipating a blitzkrieg attack from Hitler. However, no major battles occurred during this time.
