The "Fortuyn" ran ashore on the west river bank some distance from the bridge and its, probably only partial, explosion did little damage to the Spanish forces, but the "Hoop" drifted along the same bank between the river shore and a protective row of anchored ships forming a raft in front of the main bridge and touched the latter near the junction of the fixed wooden shore structure and the attached ships. When the time bomb aboard the "Hoop" exploded, about eight hundred troops were killed, the sconce "Santa Maria" was devastated, and the ship bridge was ripped apart over a distance of 60 metres; the blast was heard in an 80-kilometer radius. Farnese was wounded in the explosion. However, the damage to the bridge was quickly repaired, and a rebel relief fleet failed to exploit the opportunity to break through, because it was at first mistakenly thought the attempt at the bridge had been unsuccessful.
