cavalry around the Russian lines at Davout's exhausted troops; the sudden attack threw the French into disarray. Following the battle, L'Estocq's corps retreated to Preußisch Friedland to maintain coalition communications with Russia. Honours For their leadership in the battle, L'Estocq received the Order of the Black Eagle and Scharnhorst the Pour le Mérite. While the Prussian Army had been crushed at Jena-Auerstedt, L'Estocq's troops restored honor to the demoralized military. Colmar Freiherr von der Goltz wrote, "it was at Eylau in 1807, and not the War of Liberation in 1813, that the old army vindicated itself before the tribunal of history". Von der Goltz attributed the success to Scharnhorst's planning and L'Estocq's initiative and willingness to attack. After the coalition defeat in the Battle of Friedland and the humiliating Treaties of Tilsit, L'Estocq was part of an investigatory commission into the causes of Prussia's defeat in the Fourth Coalition. Because of his successful cooperation with L'Estocq, Scharnhorst successfully lobbied for attaching a chief of staff to each field commander in 1813. L'Estocq became Governor of Berlin on 12 November 1808, and of Breslau in 1814. After his death in Berlin on 5 January 1815, L'Estocq was buried in the cemetery of the city's garrison church three days later.
