Admiral Sampson’s orders were to refrain from making any land attack so long as the batteries on shore did not attempt to molest his ships; but in case the Spaniards fired on his vessels, to destroy the offending fortifications.

These orders were not issued until the Spanish fire at different Cuban ports became so irritating to the American bluejackets that discipline was, in a measure, threatened; but as soon as the men learned that they were no longer to remain passive targets for the Spaniards, but were to return any shots against them, all grumbling against inaction ceased.

It was not Admiral Sampson’s original intention to attack San Juan. He was looking for bigger game than the poorly defended Porto Rican capital. His orders from the Navy Department were to find and capture or destroy the Spanish squadron that was en route from the Cape Verde Islands, and it was this business that took him into the neighbourhood of San Juan, he being desirous of learning if the Spanish squadron were there.

The fleet arrived off San Juan before daybreak on Thursday. The tug Wampatuck was ordered to take soundings in the channel, and at once proceeded to do so. She was fully half a mile ahead of the fleet when she entered the channel, and those aboard of her kept the lead going at a lively rate.

It is supposed that Admiral Sampson had no intention at that time of entering the harbour itself, his object, when he found that the Spanish squadron was not at San Juan, being to learn for future use exactly how much water there was in the channel, and if any attempt had been made to block the way.

At all events, while the Wampatuck was engaged in [pg 125]this work she was seen by the sentries at the Morro, and a few minutes later was fired on.

Then, and not until then, did Admiral Sampson determine to teach the Spaniards a lesson regarding the danger of firing on the American flag.

“Quarters!” rang out aboard the war-ships almost before the report of the Morro gun had died away, the flag-ship having signalled for action.

The Iowa opened the bombardment with her big 12-inch gun, the missile striking Morro Castle squarely, and knocking a great hole in the masonry.

Then the Indiana sent a 13-inch projectile from the forward turret, and one after the other, with but little loss of time, the remaining vessels of the fleet aided in the work of destruction.
