Why surprise fails at sea

Surprise is an advantage rather than a substitute for sound intelligence and adequate force. It may fail because the target has warning, because the attacker misunderstood the situation, or because planners expected surprise to compensate for other weaknesses. The video tests that argument through three English or British operations against Spanish possessions and treasure movements. Unloaded cargo, disease, prepared defenses, and poor execution repeatedly erase the hoped-for benefit. This distinction separates later tactical victories from failed attempts to seize treasure or conquer territory.
