In British writing, phoney war is a common phrase referring to either a period of inaction between two wars or a tense period of conflict not involving actual fighting. It was initially used to describe the period between the start of the Second World War and the Battle of France (i.e., roughly between September 1939 and April 1940) when there seemed to be surprisingly few hostile engagements between the Western Allies and Nazi Germany.
