The invasion of France by German forces commenced with the strategic crossing of the Meuse River, a pivotal point in their military campaign. This operation was part of the larger Battle of France, which saw German troops utilizing blitzkrieg tactics that focused on rapid mobility and the element of surprise. On the same day, British Prime Minister Winston Churchill addressed the House of Commons to prepare the nation for the challenges ahead. His speech was both a call to arms and a sober acknowledgment of the sacrifices that lay before them. Churchill's impassioned delivery sought to unite a shaken country in the face of a formidable enemy.

The German strategy was characterized by coordinated attacks that utilized tanks and aircraft to break through enemy lines swiftly. The crossing of the Meuse was not only a significant military maneuver but also symbolized the disastrous potential of the German war machine. Meanwhile, Churchill's speech underscored the determination of Britain to confront Nazi aggression head-on. It was a moment of clarity, where the dire situation was made apparent, but so was the resilience that would characterize British efforts in the subsequent months.

As the German forces advanced rapidly, there was a growing sense of urgency in Allied circles. Churchill’s words were intended to galvanize support for the war effort, and his ability to rally the public became a hallmark of his leadership during World War II. The events of this day represented both a military milestone for Germany and a turning point for Allied resolve, showcasing the importance of leadership during times of crisis.
