I used a number of references as note above. I have the Osprey Men at Arms 206 on the Hanoverian army and that is where I got some of my basic information for 1813, I also had researched the OB for the Battle of Gohrde in an earlier post. I also used some references from the following links as listed above: the Napoleonic Series, Gen de Brigade forum, a nice clickable reference to the Battle of Waterloo OOB, the Mont St Jean site and this pamphlet by WJ Rawkins. I also used Siborne's well known uniform table as follows, although there is some debate about it's accuracy.
