Germany invaded the Allied nation of France and the neutral Low Countries. In France, Luftwaffe aircraft destroyed many French aircraft on the ground. German tanks crossed into neutral Luxembourg with relative ease, reaching the edge of the Ardennes Forest; the royal family of Luxembourg was evacuated to the south. In the Netherlands, German paratroopers quickly secured key bridges and airfields around Rotterdam and the Hague, but the plan to land troops at the Ypenburg airfield to capture the Dutch political leaders was foiled when Dutch fighters shot down 18 German Ju 52 transport planes; German tanks penetrated more than 10 miles into the Dutch border by the end of the day. In Belgium, 10 gliders landed 78 German airborne soldiers atop Fort Ebel Emael at the crossings of the Albert Canal and the River Meusse, pinning down the 700 Belgian defenders. British and French leaders enacted the Dyle Plan in response to the invasion, moving troops toward the Dyle River in Belgium where they were to form a defensive line.
