In the short peace of 1814-1815 Bülow was at Königsberg as commander-in-chief in Prussia proper. He was soon called to the field again, and in the Waterloo Campaign commanded the IV Corps of Blücher's army. He was not present at Ligny, but his corps headed the flank attack upon Napoleon at the Battle of Waterloo, and bore the heaviest part in the fighting of the Prussian troops around Plancenoit. He took part in the invasion of France, but died suddenly on 25 February 1816, a month after his return to the Königsberg command.
