On the Prussian Infantry 1869

From the publishers:
 
On the Prussian Infantry 1869 is the second of two titles penned by a Prussian infantry officer Captain Theodor May that challenged the Prussian military establishment in the wake of the Campaign against Austria in 1866. This particular title focuses on the tactical formations employed by the Prussian infantry during 1866 including the company column the deployed line and skirmishing formations and suggests revisions to them.
This edition features a comprehensive new introduction by Duncan Rogers that surveys the controversy triggered by May's writings and sets them in the context of contemporary military literature.
