The Axis were very aggressive in the Winter of 1939, declaring war on both the Netherlands and Belgium and attacking all three Holland, Flanders, and Ardennes territories. Due to the Winter conditions and French/BEF reinforcements into Flanders, only the Ardennes attack was successful. The Germans continued their aggressive attack by launching a Winter mechanized attack into France which took them to the gates of Paris. Some significant infantry casualties in Flanders and Holland were taken, but the Germans only suffered a panzergrenadier loss or two with their blitzkrieg through the Ardennes.
In the Med, the Italians declared war on Greece, but Greek AA drove Italian bombers away from the ships in port at Athens. Italian units mass on the French border, which keeps the French army honest in the South. In the Pacific, the Japanese mass for a successful invasion of Honan and the Chinese army retreats toward Chunking.
