Off Trondheim, 08:00 April 8th, 1940
"No captain can do very wrong if he places his ship alongside that of the enemy". The captain of HMS Ardent when forced to action against the Admiral Graf Spee proves true to Nelson's words when he rams his ship on the German pocket battleship. Graf Spee suffered extensive damage, but Ardent was sunk by German fire without managing to report its engagement to the admiralty.
Off Lillesand, 10:00 April 8th 1940
The German troopship, MS Rio De Janeiro, was supposed to support German landing on Bergen. Instead it had met HMS Tarpon. The British boat would sink it with a pair of torpedoes. No report of the sinking would reach the admiralty till the next day as Tarpon was under strict orders to maintain radio silence.
Norwegian Sea, 14:00 April 8th 1940
The British Home fleet turned Northwest following reports of sighting a group of German ships, it was assumed the German goal was to slip the blockading forces and break into the Atlantic. Meanwhile plans for the landing of troops to Norway continued, the Scots Guards and supporting units had already been loaded on 4 Royal Navy cruisers which should be sailing out within the next day.
Oslo, 04:00 April 9th 1940
The Norwegian cabinet was in session for the past several hours after news had reached it of the navy engaging German ships outside Oslo. Finally the decision to order a partial mobilization was issued. Colonel
Rasmus Hatledal the chief of the general staff had instead asked for a general mobilisation but to no avail, could only say that he'd order the army to start mailing call-up notes to reservists right away only to be met by shock. The army could conduct the ordered mobilization only by mail? It was Hatledal's turn to be shocked, hadn't the ministers just order a secret partial mobilization? It took defence minister
Birger Ljungberg to explain the vagaries of the mobilization system, and that partial mobilization was allowed only by secret call-up. One more hour would be lost before the cabinet issued the order for a general mobilization. Elsewhere in Norway fighting was already underway.
Narvik, 06:00 April 9th 1940
An hour ago 10 German destroyers had sunk the two Norwegian coastal defence ships protecting the city and landed 2,000 Gebirgsjäger. The Norwegian commander, a colonel Sudlo, had surrendered Narvik shortly afterwards. He would be put on trial on charges of high treason for his action. The German ships start immediately refuelling from the couple of German tankers that had put into the port before the invasion under the guise of merchant ships, while the battleships Scharnhorst and Gneisenau provided distant cover to the force. It was estimated that it would take 18 to 20 hours to refuel all ten ships. The battleship Renown backed by 5 destroyers turned toward Narvik, while the 2nd destroyer flotilla with 5 more destroyers was ordered into Narvik. Renown's sister Repulse, escorted by 4 more destroyers and the light cruiser Penelope turned north to join Renown but she was still much further out.

Copenhagen, 08:30 April 9th 1940
The Danish government surrendered, 6 hours after the country had been invaded by the Germans. Had not Zanzibar surrendered to Britain in 38 minutes back in 1896 it might had been the shortest war in history...
Kristiansand, 14:00 April 9th 1940

Köln had run aground under Norwegian fire but the town had nevertheless fallen to the Germans.

Drøbak Sound, April 9th 1940
