THE DEFENSE OF GIBRALTAR:  EXPERIMENTAL NAVAL AND MILITARY OPERATIONS.

[Illustration:  The defense of Gibraltar—­experimental Naval and military operations.]

A novel and interesting series of operations was carried out at Gibraltar a few weeks ago, with a view to test the promptitude with which the garrison of the famous Rock could turn out to resist a sudden attack by a powerful iron-clad fleet.  The supposed enemy was represented by the Channel Squadron, under the command of Vice-Admiral Baird, and consisting of H.M.S.  Northumberland (flag ship), the Agincourt, Monarch, Iron Duke, and Curlew.  The “general idea” of the operations was that a hostile fleet was known to be cruising in the vicinity, and that an attack on the Rock might be made.  The squadron left Gibraltar and proceeded to the westward, returning to the eastward through the Straits under cover of the night.

The Governor of Gibraltar, General the Hon. Sir Arthur Hardinge, issued orders for the whole garrison to stand to their arms at dawn, and subsequent days, until the attack should be made; but by his express command no batteries were to be manned, or any troops moved from their alarm posts, until the signal was given that an attack was imminent.  The alarm signal ordered was that of three guns fired in rapid succession from the Upper Signal Station on the summit of the Rock, to be followed, after a short pause, by two more shots.  It was a matter of complete uncertainty as to the direction from which the attack would be made.

Every detail was carefully carried out, as if the impending attack was a real affair.  The telegraphic communication between the various parts of the Rock was supplemented by signalers; arrangements were made for the ready supply of reserve ammunition for all arms; and the medical authorities established dressing stations, at numerous points of the Rock, to render “first aid” to those who might chance to be numbered among the “wounded.”  Day broke with a “Levanter,” and the heavy clouds hanging about rendered any distant view a matter of difficulty.  However, before it had become actually daylight the alarm guns gave notice that the enemy had been sighted.  The troops turned out with great promptitude, being all at their assigned stations in less than a quarter of an hour, and were shortly ordered to various points commanding the east side of the Rock.  As day broke, the hostile ships were to be discerned steaming in single line ahead, from the northeast, along the back of the Rock, and about 5,000 yards from it.  The flag ship, followed by the Monarch and the Agincourt, proceeded toward Europa Point, while the Iron Duke and the Curlew stood close in to the eastern beach, so as to engage the northern defenses of the fortress.  The first shot was fired by the flag ship, shortly before six o’clock in the morning, at the southern defenses.
