Arms of Precision mb-artistname S Woodward Pat 'raises his roof' by'Arms of Precision', 1878. The setting is a 'Sham Fight, Aldershot'. The Brigade Major is saying to the Officer of Artillery: If you Fire by the Compass due South, at a range of Two Miles, the Enemy must retire!

From Punch, or the London Charivari, November 2, 1878.
