Yet, on his side, he had some cause for complaint.

In the previous summer, Alexander led him to expect the active aid of 35,000 Russian troops for a campaign in Norway: but, mainly at the instance of England, he now landed in Pomerania and left Sweden exposed to a Danish attack on the side of Norway.

He therefore suggested an interview with the allied sovereigns, a request which was warmly seconded by Castlereagh.[332] Accordingly it took place at Trachenberg, a castle north of Breslau, with the happiest results.

The warmth of the great Gascon's manner cleared away all clouds, and won the approval of Frederick William.
There was signed the famous compact, or plan, of Trachenberg (July 12th).

It bound the allies to turn their main forces against Napoleon's chief army, wherever it was: those allied corps that threatened his flanks or communications were to act on the line that most directly cut into them: and the salient bastion of Bohemia was expressly named as offering the greatest advantages for attacking Napoleon's main force.
