The apparatus atop the tripod foremast fitted to the USS Minneapolis, rotated to follow the cross-bearing target, as in presenting a course that was tangent to the circle the apparatus created at its endpoints as the boom portion of it so rotated. Bradley A. Fiske was not the man at the apparatus’ superimpositor. That honor went to ASM2C Hathaway Jones, who had the strong eyesight and the stubborn endurance to man the post during this demonstration exercise. The exercise was by “invitation only” and featured a select group of notables.
And from the Army, because there were a few science-minded soldiers among the horse troopers and Apache chasers;
And just to keep everyone with the purse strings in the loop, who would have to approve the money needed for the fleet; if this cross-hair hare-brained experiment worked, there were a couple of Congress-cretins as observers.
Two featured observers were not aboard the
USS Minneapolis. Messrs.
Alfred Thayer Mahan and
Philo McGiffin had the dubious honor of being aboard the
USS Choctaw. The tugboat was not the target. That was a floating catamaran of dubious construction, with a large 10 meter by 10 meter slat-board timber frame conglomeration of Maryland local lumber sloppily nailed together and hopefully not expected to survive the current experiment. The “victim”, which was supposed to simulate a British Royal Sovereign class battleship aim point, by LTCDR Fiske’s calculations, was about 200 meters astern, of the
USS Choctaw by floating tow-line length being pulled along at 3 m/s or about 5.8 knots.
The
USS Minneapolis hoped to hit the target sled and miss the
USS Choctaw by that same towline distance length. Previous experiments, which LTCDR Fiske had been most careful to omit in his reports, had results in which the tow ship, the unfortunate USS
Wicomico had been thoroughly and repeatedly line-shot by mistake and sunk, because the idiot at the superimpositor placed the progress-intended-motion (PIM) bar in the aiming reticle on the tow ship instead of the sled. If there was ever system-proof-positive that human error was the reason that the USN resisted innovation with extreme caution and was justified to so do, the loss of the USS
Wicomico provided the needed latest evidence.
The experiment was under hopefully more rigorous rigidly controlled conditions. ASM2C Hathaway Jones was thoroughly trained, as the aiming rate, in the proper procedures. The tracking party, led by Fiske personally, was prepared to quadruple check each angle solution and there was ASM1C Carter Powell on the fly bridge with a Bell handset wired into the ship's intercom system, he to watch the results through a specially mounted telescope and who was supposed to look at each salvoed war-shot's results and yell on the telephone to "Cease fire!" ; if a salvo-out did a repeat performance of the USS
Wicomico upon the USS
Choctaw.
At 1100 hours the USS
Minneapolis and the USS
Choctaw assumed parallel courses in the middle of Chesapeake Bay at speeds of 5 m/s at the ridiculous separation range of 4,000 meters. The shoot-ex was on. First shots out, were discharged at 1103 hours local time.
Over 200 meters off target, it was by ASM2C Hathaway Jones’ estimate and that result was confirmed by ASM1C Carter Powell and it was 3/10s mill of the angle solution astern. So.... adjust the angle of barrel elevation one crank on the elevation gear in the 15 cm gun mounts and make one half hand crank on the bearing or slue gear of the barbette table. Try again.
This salvo was short by 100 meters and 2/10 mills ahead. Fiske said to Hathaway; “Not the tug, you idiot, the sled!”
Hathaway was not too respectful in reply; “The sled is hard to see with the lenses fogging up and that tug is putting out a lot of smoke…, sir.”
“Then aim for the tail end of the smoke, damnit.” Fiske ordered.
“Yes sir… aim for the tail end of the smoke, sir!” was the sarcastic raconteur.
----------------------------------------------
Mahan glared out with binoculars at the target sled and cursed; “Come on, Fiske, make it good, third time. Too much rides on this test.” Philo McGiffin stood up from where he cowered behind cover on the fantail. Philo turned to Alfred and asked him rather calmly considering he had seen a six shot live shell salvo splash a hundred meters short of the USS
Choctaw and lash it with shell splinters; “Why the hell did you volunteer us for this detail, again?”
----------------------------------------------
Third salvo arrived at 1108 hours and it was observed that four of six shells hit the target sled (by accident?) and blew it to splinters and glory. Fiske was a success!
The first comment after the stunned silence from the result, which took a half minute to register, for these were professional men who knew how hard it was for one ship to hit another at 1,000 meters in 1897, much less at a distance of 2 and 1/2 miles (~4,000 meters), was the one Joe Wheeler made to William Shafter. He said; “You better go on a diet, general. Three hundred pounds of you sitting on a horse is not going to cut it in Cuber when we go to war. to take that place, sir!”
Shafter was nonplussed; “What makes you think we are going to war, Congressman?”
Roosevelt interrupted; “Because now we have a chance against the Spaniards. We can outshoot them and sink them.”
Shafter turned to Roosevelt to retort; “Not on land, sir. And that is where we will have to beat them, presuming the navy clears the Spaniards from the seas.”
“One problem at a time, Bill.” Nelson Miles added his own quiet remark. “Solve the navy, first, then the army can figure out how to fix Crozier’s mistakes with the Coffee gun and the Krag. I should have reassigned him to the Dry Tortugas when I had the chance last year.”
--------------------------------------------------
Tillman piped up. “How much is this going to cost us?”
The ever optimistic Fiske lied; “No more than a half million dollars to refit fifty ships, Congressman.”
Sour at the answer; Tillman said, “You mean more like two million dollars and we get twenty five ships' worth?”
Fiske was happy that he had bow-waked, because now he figured that the fire control telemeter would cost more like one million dollars and he counted on Tillman to overestimate as much as he did. If he could get Tillman to cough up a million dollars, he could refit twenty-five ships or one half of the steel navy, with enough left over to at least give the rest of the fleet height finder range-finders. That surely was a clear win for the Navy, was it not? “Agree on one million dollars, Congressman, and we can do twelve ships?”
“The battleships and the armored cruisers, we'll fund, plus whatever protected cruisers we can afford at one million dollars.” offered Tillman.
“Deal.” Fiske and Tillman shook hands on it. Fiske would vigorously wash his hands after the odious and slimy "Pitchfork" Ben Tillman departed with the rest of the suitably impressed delegation.
