Ok, it's from Wikipedia, but still is a good POD. Apparently Gustav Adolh was injured twice between June-August of 1627, during the war in Poland:
"At the beginning of June 1627, Gustav Adolf was lightly wounded while attempting a night-crossing of the Vistula in a boat near Käsemark (Kieżmark), south of Danzig (Gdańsk), and had to retreat."
And this happened during a battle near the Motlawa River on 17 and 18 August: "In 1627, near Dirschau in Prussia, a Polish soldier shot him in the muscles above his shoulders. He survived, but the doctors could not remove the bullet, so from that point on, he could not wear iron armor. Also, two fingers of his right hand were paralyzed."
So, WI Gustav Adolf had been killed in one of these incidents instead of only wounded (probably the second one is a better POD)? This was before the Swedish intervention in the 30 Years War, so would it mean a shorter conflict in Germany? Or would it mean an earlier French participation in the war?
