Early in the
American Revolutionary War, Phelps was chosen as a member of "Committee of War for the expedition against Ticonderoga and
Crown Point." The committee considered the advisability of taking
Fort Ticonderoga, then occupied by the
British, and in which there was stored a large amount of heavy artillery and other war implements. Capt. Phelps, Barnard Romance, Ephraim Buell, and Capt. Edward Mott, with others, composed this committee, Capt. Mott acting as chairman. £300 was raised from the Public Treasury though guaranteed by several patriotic gentlemen. This fund was placed in the hands of Capt. Phelps and Barnard Romance, with the request that they should go north and press forward this project. This resulted in the great and bloodless victory — the
capture of Fort Ticonderoga.
Captain Phelps acted as a spy in the campaign. Sent out to reconnoiter the southern part of
Lake Champlain, he stopped overnight at a farm house some little distance from Fort Ticonderoga. Some British soldiers occupied rooms adjoining Phelps, where they were having a dinner party. Phelps heard them discuss the condition of the fort, and the position taken by the rebels, as they styled the people. Early the next morning, Phelps visited the fort disguised as a peddler.
"Pretending that his object was to get shaved, he avoided suspicion, and had an opportunity to ascertain the construction, strength, and force of the garrison. And he had the good fortune to elude detection, though as it afterwards appeared, his presence had began [sic] to excite mistrust before he left the garrison."
While returning through the fort, the commander accompanied him talking with him about the rebels, their object and movements. Phelps, seeing a portion of the wall in a dilapidated condition, remarked that it would afford a feeble defence against the rebels, if they should attack in that quarter. The commander replied, "Yes, but that is not our greatest misfortune. All our powder is damaged, and before we can use it, we are obliged to dry and sift it."
Phelps soon after left the fort, employing a boatman to take him down the lake in a small boat. He entered the boat in full view and under the guns of the fort. He requested the boatman to exert himself and terminate the journey as soon as possible. The boatman then requested him to take an oar and assist. This Phelps declined to do, being in full sight of the fort, by saying he was no boatman. After rounding a point that intercepted a view from the fort, Phelps proposed taking an oar, which he did, and being a strong active man as well as a good oarsman, he excited the suspicion of the oarsman by his efficient work, who remarked with an oath, 'You have seen an oar before now, sir.' This excited the suspicion of the boatman at the time that he was not a good and loyal citizen, but fear of superior strength prevented an attempt to carry him back to the fort. This he confessed to Capt. Phelps after the surrender of the fort. Capt. Phelps returned safely to his command, reported the information he had gained to General
Ethan Allen, resulting in the great and glorious victory before referred to."
