In this Christmas bonus episode, I answer listener questions.

In May 1944, Allied forces in Italy began an offensive that finally broke the Gustav Line. Soon Americans were marching into Rome. At the same time, Allied forces in Britain were making final preparations for the invasion of France.

In this episode, we look at some of the preparations both sides' militaries were making for the coming invasion of France, as well as the tricky problem the Allies faced in keeping Charles de Gaulle on board.

As America geared up for war, and then entered the war, African Americans fought to claim a role in the battle against fascism.

During the interwar period, African Americans pushed back against the US military's explicit racism.

Boogie-woogie went mainstream in America during the war, as evidenced by the music of Glenn Miller and the Andrews Sisters.

The Americans were on the offensive in the Southwest Pacific, and after Tarawa, in the Central Pacific. As they advanced, Japanese military leaders scrambled to find a way to stop the Americans.

As soon as Allied leaders chose Normandy as the site of the Operation Overlord invasion, British intelligence set to work convincing the Germans that the invasion would be somewhere else.

The Allied campaign in Italy stalled, and British and American leaders were searching for a way to break the stalemate on the peninsula. Winston Churchill suggested an amphibious invasion behing enemy lines.

The war era (1939-45) saw the beginning of the end of the big band era. Part of this decline was due to two key strikes in the music industry.
