along the whole length of the ship, with every shot likely to cause the maximum carnage. The opportunity was a passing one and the most had to be made of it. With the coming of HMS ''Dreadnought'', with her turreted main armament, the heavy guns were directed by firing a salvo of half-broadside in order to observe the fall of shot, allowing enough time to adjust for range and direction before firing the other half-broadside. This way, shells were kept in flight while each half-battery was reloaded. Reloading a battleship guns, arriving at a firing solution and lining the guns up to fire took as long as 30 seconds, especially when the fall of shot needed to be observed and corrections made before firing again. A target ship moving at traveled in 30 seconds, and would often maneuver to "spoil" the range measurement. The "spread" of the salvo would have one shot fire "over" the estimated range, one shot "under", and two on the estimated range. When a four-shot "salvo" "straddled" the target with one splashing over, one splashing under and two landing on or near the target, fire control officers knew they had the correct range.
