Sketch of 'Reconnaissance of the Blackwater Valley', with critical comments by the tutor, for a Staff College course, by Captain Archibald Crawford RA, Staff College, April 1891

Archibald Crawford won prizes for landscape drawing and military topography while he was a cadet at the Royal Military Academy Woolwich in 1891. He took further courses in mapping at the Army's Staff College - its school for senior officers - before teaching there himself in 1905.

The Board of Ordnance set up the Royal Military Academy Woolwich in 1741 in order to produce 'good officers of Artillery and perfect Engineers'. The School of Military Survey was set up there in 1833 to train cadets in surveying, sketching and mapping.
