Swedish troops led by Bernadotte took part in the Napoleonic Wars in 1813 and 1814, wherein the Crown Prince authored the Allied Campaign Plan, known as the Trachenberg Plan, and commanded the Allied Army of the North. Bernadotte's army fought against the French in the fall of 1813 and defeated them at the Battle of Grossbeeren, Battle of Dennewitz and played a key role in the mammoth Battle of Leipzig. Bernadotte then led an invasion of Denmark. Sweden forced Denmark to hand over Norway by the Treaty of Kiel. This was recognised by the Allied powers at the Congress of Vienna. Since this time Sweden has not taken part in armed warfare (with the exception of peacekeeping).
