Clyde,
I tried the British attack on the German fleet on UK1. With 1 DD, 1 BB, 2 CA, 3 FTR, and 1 SBR attacking the fleet it went very well. The German AC, BB, CA and were burning wrecks and his planes went down in the ocean. At that point Germany must build a new navy, which means less money for transports, or give up Sea Lion.
Nevertheless it is a risky attack in that both sides are about equal strength. But when you realize you have nothing really to do with the remainder of the British navy and that you can retreat after the first round of combat to save your planes then it is not such a bad attack. Roll well the first round, stay and wipe out the German navy. Roll bad, take the losses on the British navy and retreat the planes back to England.
Also it is not so easy for the Germans to defend against even when they know it is coming. One of the fighters flies on to Italy after the battle. A good many of the others land in Belgium/Holland preventing them from scrambling to help the German navy’s defense. For example any fighters or tactical bombers that attack London proper in a raid or attack the DD and TR near England cannot land in Western Germany. They must land in Holland/Belgium.
So if he commits a number of fighters to the strategic bombing raid on London, at least those planes must land on a carrier or Holland/Belgium. It is something at least.
