I'm playing Rasputitsa's Fall Gelb Mod, which starts the war in the beginning of 1940, and Hitler has kicked off the invasion of the Low Countries and France.
It is now April 1st. Belgium has fallen, The Netherlands is soon to follow, and two British divisions are trapped in the Netherlands. The rest of the British expeditionary force had to beat a hasty withdrawal from Belgium back to the UK. German Panzers and infantry are striking into France.
Going is slow because of the winter conditions. This is not blitzkrieg, the Panzers have been on occasion able to obtain minor penetrations where holes have been blown in the French line.
I do expect to be able to take France by mid June, leaving me with two options: plan for 1941 Barbarossa; Sealion.
I've never done Sealion in all my years of playing ToF, but if I can gain air superiority over the Channel and southern England, I'm going to try it.
I will have 4 months to prepare 3 infantry corps and 1 infantry division and 1 parachute battalion, gather together 10 amphibious points - for the first wave to embark on Sept 1, and land on Sept 7 as shown in the screencap.
The infantry division will be tasked with cutting the rail line between London and Southampton. Two corps will flank Southampton, and the Parachute battalion will land north of Southampton. If recon shows Southampton poorly defended, the third corps will land directly in the port area.
Using Rasputitsa's mod, I am able to build up a minor port capability on any hex where I can do an amphibious landing, but I don't think I'll need that UNLESS I can't take Southampton by Sept 14th. If needed I'll build up the small port on the landing hex where the division came in, but until then I'll rely on beachhead supply and total air superiority. But really, if I can't take Southampton by the 14th, the invasion has probably failed. I can't afford followup waves of amphibious units.
