What undermined Harold's plan to attack William off guard?

• A. William had watchers tracking them
• B. Harold's horses were exhausted
• C. The weather changed suddenly
• D. An illness weakened Harold's men

Answer: (A)

Surprise attacks hinge on secrecy. If the enemy’s movements are watched or tracked, the attacker loses the element of surprise and the defender can prepare. In this case, William had watchers tracking Harold’s approach. That forewarning meant Harold couldn’t slip in unseen to strike William while he was off guard. William could marshal his forces, choose a favorable position, and respond as Harold’s plan to surprise him began to unfold, which undermined the whole idea of catching William unaware. The other possibilities would alter the dynamics of the march or the fighters’ condition, but they don’t directly explain why Harold’s plan to surprise William failed as effectively as being watched does.
