Hunyadi leads a Hungarian-Wallachian coalition army of crusaders across the Danube into Serbia in 1448 to join forces with Skanderbeg.

Despite making effective use of mercenaries armed with handguns, the treacherous desertion of Hunyadi’s Wallachian troops enables Murad's far larger Turkish army to overwhelm his forces on October 17-20 in the second Battle of Kosovo.

The Turkish victory does not lead to the conquest of Albania, but it strengthens the Ottoman position on the Danubian frontier and effectively halts what will prove the last major effort by Christian crusaders to free the Balkans from Ottoman rule and to relieve Constantinople.
