The meeting of Treves occured in 1473 between the Holy Roman Emperor and Charles the Bold Duke of Burgundy. At the meeting Charles made promises about imitating John the Fearless and going on Crusade against the Ottomans. He promised to lead the campaign himself and commit a few thousand men to the venture. The Emperor also promised to commit some forces as well. Charles afterwards though made the decison that if he went it would have to be after he made peace with French King Louis XI, which in the end never occured. So my question is what if Charles makes peace with Louis, never gets involved with the Swiss, and heads out? My feeling is that it would have similar results to 1396 Crusade.
