Feb-Mar 1940
February 10, 1940 : Despite Winter still holding sway, the General Staff was too eager to wait any longer. They informed Hitler that they were ready for phase I - Denmark. Hitler therefore decided made his public declaration of war. It was hoped tht Denmark would surrender at the first sign of serious force, but no such luck was forthcoming. Denmark entered a Military Alliance with United Kingdom, Iraq, France, Australia, New Zealand, Canada, South Africa, Nepal, Bhutan, Yemen and Oman.
February 11, 1940 : I. Panzer Army HQ has arrived in Kolding. We also won a battle against Denmark in Copenhagen.
February 12, 1940 : I. Panzer Corps has arrived in Odense. I. Panzer Army HQ arrived in Arhus. Hitler annexed Denmark.
Later that day the Danish fleet was found fleeing to British ports and was immediately bombed by the Luftwaffe. A series of battles occured over the next few days which ultimately resulted in the sinking of the Danish Navy.
February 14, 1940 : The KM reported the upgrading of their CAGs once again to Bf.109T / Ju.87T Stuka / Fi.167. (Improved CAG) Finally the KMs CVs have airgroups based on modern aircraft with the ability to take center stage in naval combat.
February 24, 1940 : The first batch of Infanterie Divisions has been upgraded to Infantry '41. Unfortunately, it will be a long while before the whole Heer is up to this new standard.
March 1, 1940 : KMS Hindenburg and KMS Ludendorff were commissioned, bringing the primary battleline up to 6 BB, 2 BC and 2 CA. Plans are to build 2 more Bismarck class vessels before switching to either H, or H-44 class.
March 6, 1940 : The UK, taking advantage of our rather limited range of operations, launched their own amphibious operation against Iceland today. We have lost control over Reykjavik to United Kingdom. Until Norway is taken there is little hope of retrieving the base in Rekjavik. For the time being, it is not really essential anyhow. It will be, however, after we take the British Home Isles. The UK completed their conquest of Iceland by occupying Hofn on the 10th. This news prompted Hitler to order a go-ahead on the second phase of Scandinavian operations. Oslo is ice free, but Narvik will still be frozen.
March 11, 1940 : As the KM sailed north with the invasion force for Narvik, they stumbled into a large French task force in Helgoland Bight. The upgraded CAGs really showed their effectiveness in this fight. The French force had no CVs. They lost the Ocean(BB), Bretagne(BB), Jeanne d'Arc(CL), Foch(CA), and 7ème Flotille des Contre-Torpilleurs(DD) before getting the hint and running for their lives. The invasion force continued to its destination. (tactical note - due to the short range of the G7 class DD, the KM disbanded that unit so that they could reach the shores of Narvik. Modern replacement DDs are already on the slipways.)
March 14, 1940 : With both landing forces and covering fleets in position, Hitler declared war on Norway. The battles on the beaches of Oslo and Narvik were both won by the end of the day. The German Marines have been earning their pay, and will continue to have opportunities to do so.
March 15, 1940 : With 60 U-boats now operating in the Western Approaches, the wolfpacks scored their first convoy success, sinking 8 transports and 0 escorts. The Baltic Flotilla also met a suicide mission by the Norwegian Navy and quickly sank the KNM Norge(CA), KNM Eidsvold(CA).
March 16, 1940 : Another U-boat success, our forces in West Biscaya Basin have sunk 9 transports and 0 escorts.
March 17, 1940 : I. Mountain Corps has finished unloading in Narvik. II. Marine Corps has finished unloading in Oslo. Hitler annexes Norway. Forces immediately begin redeploying to positions for the invasion of Sweden. The Norwegian submarine forces make a desperate dash through the Kattegat to reach UK bases. They are caught by land based airpower and the Baltic Flotilla and sunk.
March 18, 1940 : U-boats operating in the West Biscaya Basin found the French Battlecruiser Dunkerque sailing alone and sank her.
March 19, 1940 : U-boats en route to convoy areas were repeatedly harrased by UK and French naval forces as they attempted the Channel passage. A day long series of battles took place which ultimately resulted in the sinking of a handful of UK and French DDs, plus HMS Diomede(CL), HMS Suffolk(CA), HMS Exeter(CA).
March 20, 1940 : HMS Courageous(CV) was found sailing in the West Biscaya Basin and sunk by U-boats. Hitler is struck by a sense of De Ja Vu. (I find it interesting that both Courageous and Glorious met with their historic fates.)
March 22, 1940 : After further review of the tactics and equipment of CV operations, the KM revises and upgrades their CAGs once again. CVs now operate Bf.109T / Ju.87T Stuka. The older Fi.167 were found wanting in recent operations, while the Ju.87T proved its ability to act as either a dive bomber or a torpedo bomber as the situation demands.
March 30, 1940 : Another convoy attack. Our forces in West Biscaya Basin have sunk 11 transports and 0 escorts. Also on this day, Hitler declares war on Sweden. By the end of the day, battles have been won in Malmo (as an entire Panzer Army is lifted across the Kattegat), Stockholm (by Marine landing), and Kiruna (by overland attack of Mountaineers).
April 1, 1940 : We won battles against Sweden in Göteborg and Karlskrona.
April 2, 1940 : U-boats score again. Our forces in East Celtic Shelf have sunk 9 transports and 0 escorts. We also win a battle in Gotland and complete the occupation of Stockholm. Hitler is very pleased with the capture of large stores of Metals. The German economy now runs a fine line only in Rare Materials.
April 3, 1940 : We won battles against Sweden in Skövde, Amal and Jonkoping. HMS Gustav V(BC) was found and sunk just off the Swedish coast.
April 4, 1940 : I. Mountain Corps has arrived in Sveg.
April 5, 1940 : I. Mountain Army HQ has arrived in Ludvika. We won a battle in Karlstad, but lost to a counter-attack in Gotland.
April 6, 1940 : We won a battle against Sweden in Falun.
April 7, 1940 : U-boats in the West Biscaya Basin sink HMS Carlisle(CL). I. Mountain Corps arrives in Falun, occupying the last Swedish objective. Hitler annexes Sweden the following day. Immediately all forces are ordered to make all haste to the western border area. Spring has arrived and good campaigning weather is wasting. Forces are ordered to be ready for Operation Fall Gelb no later than April 20.
April 15, 1940 : Garrisoning of occupied territories continues to drain away manpower and supplies. Currently 312,000 men in 26 division+brigades are on anti-partisan duty. Reserve manpower has fallen to 800,000.
April 19, 1940 : A final tally of armed forces ready for Operation Fall Gelb is taken. The Luftwaffe has 1200 Bf.109G Fighters, 2400 Tac Bombers (mix of Do-17/He-111/Ju-88), and 700 Do.217 Nav Bombers. The Heer has allocated to the operation 1 Marine Army (Mar 39), 1 Mountain Army (Mtn 39), 2 Panzer Army (Pz.III), and 3 Infantry Army (mix of Inf 39/41). Including HQ units this comes to 85 divisions. (Historic force was 94 divisions, but with only half the tank force...this should be winable.) Kriegsmarine reports approximately 50 surface units ready for action and 24 U-boat flotillas, plus transports.
