Mobile's defenders were tactically dangerous, but their strength existed inside a much larger strategic imbalance. Union sea control let Farragut gather monitors and wooden warships from a fleet supported by deeper shipbuilding and repair capacity. Confederate losses were much harder to replace, and European procurement could be interrupted before purchased rams reached the Atlantic. Winning at sea depended on the industrial and diplomatic system able to sustain a squadron after the first engagement.

Sea control turns replacement depth into power
The Union could concentrate ships at Mobile and replace losses, while Confederate and overseas efforts could not sustain an equivalent fleet.
