Editorial note — Chapter VI · THE FIRST BATTLE OF MANASSAS OR BULL RUN
Reading edition
By effective range is meant the distance where, under ordinary conditions, the enemy’s losses are sufficient to stop his advance. The effective range of Brown Bess was about 60 yards. The American rifled artillery was effective, in clear weather, at 2,000 yards, the 12-pounder smooth-bore at 1,600, the 6-pounder at 1,200.
