Who are the great generals?

[William F. Owen]

Regular British officers serving in the First and Second World Wars would have studied Lee and Jackson's campaigns at staff college, which became part of the curriculum when Colonel Henderson was a staff college instructor.

Pre- WW1 Regular Officers alone would have studied Lee and Jackson because Hamley's Operations of War (6 editions between 1867-1909) was the required Staff Collage text prior to 1898.I strongly suspect Henderson would have taught using Hamley's text.

BTW, I have the 1909 edition. It makes current US/UK writing on campaign planning and operations, look like a child's finger painting in comparison.
