Still the early campaings of WWII were seldom very bloody or very intense fighting occurred somewhere:
- Poland: the Bzura outbreak attempt perhaps,
- Norway: the sinking of the Blücher (1 incident) and some desperate fighting for Narvik, but only minor units involved
- Netherlands: in Rotterdam was some intense fighting for the bridges by minor units.
- Belgium: none
- France: none, perhaps the German 2nd offensive after reaching the Sea met stiff resistance by the defenders of Dunkirk and the French line north of Paris. In 1942: Dieppe!
- Balcans: none except for the heavy fighting for Maleme on Crete and in 1944 the battle for Belgrado;
- North Africa: none, except for El Alamein (the British attack) and the really tough battles for a dozen passes and hills in Tunesia, which were feared objects!
- Italy: a long list (at least 100) of viscious fights for some hills, mountains, fortified villages and towns all involving minor units except for Anzio and Cassino.
- France 44: a really long list for many villages in Normandy (at least 100) and severe fighting in breakout battles like Falaise, Valence and Mons, or fortified ports like: Cherbourg, Brest, Toulon, Dunkirk/Boulogne
- Netherlands and Belgium: the rivers (Arnhem) and Ardennes saw some heavy fighting for a dozen towns.....
- Russia: at least 1000-1500 places were extremely heavy fighting took place: even underground! Mostly by (many) major combat units too: near Leningrad, Moscow, Stalingrad, in the Caucasus, Ukraine, Crimea and Carpathians (Dukla Pass). Cherkassy/Korsun, Sevastopol, Stalingrad, Brody and Kursk were among the most notorious places......
- Rumania & Moldavia: terrible fighting in august 1944 with skyhigh casualties in a short period of time.
- Austria, Tjecho-slovakia and Hungary: some less than Germany but also quite intensive (along lake Balaton, around Prague, Ostrava) with many very ugly and desperate fighting (Budapest)
- Germany (& former Poland): along the borders: terrible fighting on a massive scale and with enormous high casualties (especially in the East: East Prussia, Pommerania, Silesia, Warswa, Breslau)!!
In the interior:virtually no fighting or resistance except for Berlin.
- Oceans: the sinking of the Royal Oak, Glorious, Hood, Bismarck, Barham, Scharnhorst and Tirpitz.
- Air: the mass air battles over Germany and the destruction of big historic cities like Hamburg, Berlin, Dresden and Magdeburg,
but also Pforzheim, Darmstadt, Kassel, Mainz, Würzburg and Halberstadt with terrible firestorm attacks.
