Everything went downhill for the coalition from there:
-The British sent a small expeditionary force to the continent, subdued the Dutch (which they deigned to call a "liberation") and fought an indecisive battle with a French force consisting mainly of militia. They had to retreat across the border, so the papers called it a French win, again.
-They also, in their usual annoying way, tried to stir up trouble with Prussia. Somehow they got their hands on 4 Political Points (I noticed only one Subsidies card, so I don´t know where the other 2 points came from) and brought Prussia down to level 1, giving them a 15% chance to go to war each turn. By 1806, the chance had increased to 25%, but to no avail: The Prussians wisely decided to not mess with the Emperor.
-Russia sent a very modest force to help Austria, which got annihilated together with every single Austrian army by two French armies led by Marshall Davout and Napoleon. The Austrians, bravely yet foolishly, by mid-1806 had still not surrendered, despite the fact that all their generals were dead and not a single Austrian division operational.
-Napoleon used the opportunity to create the Kingdom of Italy, and the papers promptly commented that they considered the affair so far a Marginal French Victory, which I think is a bit of an understatement.
