The German General Staff study of the First and Second Silesian Wars and the Seven Years War remains a classic secondary source for a detailed study of the conflict. Luckily it is available to download as a .pdf file from the links below. There are several different scans of several of the volumes  but I have selected those from the Robarts Library at the University of Toronto as being both the most readable and the one that provides the clearest scans of the maps at the rear of most volumes.

The study only goes up to 1760 and it was not until 1992 that the draft manuscripts of the final volumes was found in the Potsdamer Heeresarchivs/Kriegsgeschichtliche Forschungsanstalt des Heeres Manuskripte. These have now been published as Thomas Lindner (Hg.)Eberhard Kessel - Das Ende des Siebenjährigen Krieges 1760-1763 (Teil 1: Torgau und Bunzelwitz, Teil 2: Schweidnitz und Freiberg. Textband und Kartenschuber) by Verlag Ferdinand Schöningh which is as complete as the series is likely to be.

 The Leuthen memorial was destroyed by retreating German soldiers in 1945, however this photograph was taken by a visitor in 2016 and it isconsiderably worse for wear since I last saw it in 1998.
