A third suspicious letter was in an unknown tongue and even an unknown alphabet. In the Smith diary found by Charles Ward a single oft-repeated combination of characters is clumsily copied; and authorities at Brown University have pronounced the alphabet Amharic or Abyssinian, although they do not recognise the word. None of these epistles was ever delivered to Curwen, though the disappearance of Jedediah Orne from Salem as recorded shortly afterward shewed that the Providence men took certain quiet steps. The Pennsylvania Historical Society also has some curious letters received by Dr. Shippen regarding the presence of an unwholesome character in Philadelphia . But more decisive steps were in the air, and it is in the secret assemblages of sworn and tested sailors and faithful old privateersmen in the Brown warehouses by night that we must look for the main fruits of Weeden's disclosures. Slowly and surely a plan of campaign was under development which would leave no trace of Joseph Curwen's noxious mysteries.
Curwen, despite all precautions, apparently felt that something was in the wind; for he was now remarked to wear an unusually worried look. His coach was seen at all hours in the town and on the Pawtuxet Road , and he dropped little by little the air of forced geniality with which he had latterly sought to combat the town's prejudice. The nearest neighbours to his farm, the Fenners, one night remarked a great shaft of light shooting into the sky from some aperture in the roof of that cryptical stone building with the high, excessively narrow windows; an event which they quickly communicated to John Brown in Providence . Mr. Brown had become the executive leader of the select group bent on Curwen's extirpation, and had informed the Fenners that some action was about to be taken. This he deemed needful because of the impossibility of their not witnessing the final raid; and he explained his course by saying that Curwen was known to be a spy of the customs officers at Newport, against whom the hand of every Providence skipper, merchant, and farmer was openly or clandestinely raised. Whether the ruse was wholly believed by neighbours who had seen so many queer things is not certain; but at any rate the Fenners were willing to connect any evil with a man of such queer ways. To them Mr. Brown had entrusted the duty of watching the Curwen farmhouse, and of regularly reporting every incident which took place there.

The probability that Curwen was on guard and attempting unusual things, as suggested by the odd shaft of light, precipitated at last the action so carefully devised by the band of serious citizens. According to the Smith diary a company of about 100 men met at 10 p.m. on Friday, April 12th, 1771, in the great room of Thurston's Tavern at the Sign of the Golden Lion on Weybosset Point across the Bridge. Of the guiding group of prominent men in addition to the leader John Brown there were present Dr. Bowen, with his case of surgical instruments, President Manning without the great periwig (the largest in the Colonies) for which he was noted, Governor Hopkins, wrapped in his dark cloak and accompanied by his seafaring brother Esek, whom he had initiated at the last moment with the permission of the rest, John Carter, Capt. Mathewson, and Capt. Whipple, who was to lead the actual raiding party. These chiefs conferred apart in a rear chamber, after which Capt. Whipple emerged to the great room and gave the gathered seamen their last oaths and instructions. Eleazar Smith was with the leaders as they sat in the rear apartment awaiting the arrival of Ezra Weeden, whose duty was to keep track of Curwen and report the departure of his coach for the farm.
About 10:30 a heavy rumble was heard on the Great Bridge, followed by the sound of a coach in the street outside; and at that hour there was no need of waiting for Weeden in order to know that the doomed man had set out for his last night of unhallowed wizardry. A moment later, as the receding coach clattered faintly over the Muddy Dock Bridge , Weeden appeared; and the raiders fell silently into military order in the street, shouldering the firelocks, fowling-pieces, or whaling harpoons which they had with them. Weeden and Smith were with the party, and of the deliberating citizens there were present for active service Capt. Whipple, the leader, Capt. Esek Hopkins, John Carter, President Manning, Capt. Mathewson, and Dr. Bowen; together with Moses Brown, who had come up at the eleventh hour though absent from the preliminary session in the tavern. All these freemen and their hundred sailors began the long march without delay, grim and a trifle apprehensive as they left the Muddy Dock behind and mounted the gentle rise of Broad Street toward the Pawtuxet Road . Just beyond Elder Snow's church some of the men turned back to take a parting look at Providence lying outspread under the early spring stars. Steeples and gables rose dark and shapely, and salt breezes swept up gently from the cove north of the Bridge. Vega was climbing above the great hill across the water, whose crest of trees was broken by the roof-line of the unfinished College edifice. At the foot of that hill, and along the narrow mounting lanes of its side, the old town dreamed; Old Providence, for whose safety and sanity so monstrous and colossal a blasphemy was about to be wiped out.
An hour and a quarter later the raiders arrived, as previously agreed, at the Fenner farmhouse; where they heard a final report on their intended victim. He had reached his farm over half an hour before, and the strange light had soon afterward shot once more into the sky, but there were no lights in any visible windows. This was always the case of late. Even as this news was given another great glare arose toward the south, and the party realised that they had indeed come close to the scene of awesome and unnatural wonders. Capt. Whipple now ordered his force to separate into three divisions; one of twenty men under Eleazar Smith to strike across to the shore and guard the landing-place against possible reinforcements for Curwen until summoned by a messenger for desperate service, a second of twenty men under Capt. Esek Hopkins to steal down into the river valley behind the Curwen farm and demolish with axes or gunpowder the oaken door in the high, steep bank, and the third to close in on the house and adjacent buildings themselves. Of this division one third was to be led by Capt. Mathewson to the cryptical stone edifice with high narrow windows, another third to follow Capt. Whipple himself to the main farmhouse, and the remaining third to preserve a circle around the whole group of buildings until summoned by a final emergency signal.
The river party would break down the hillside door at the sound of a single whistle-blast, then wait and capture anything which might issue from the regions within. At the sound of two whistle-blasts it would advance through the aperture to oppose the enemy or join the rest of the raiding contingent. The party at the stone building would accept these respective signals in an analogous manner; forcing an entrance at the first, and at the second descending whatever passage into the ground might be discovered, and joining the general or focal warfare expected to take place within the caverns. A third or emergency signal of three blasts would summon the immediate reserve from its general guard duty; its twenty men dividing equally and entering the unknown depths through both farmhouse and stone building. Capt. Whipple's belief in the existence of catacombs was absolute, and he took no alternative into consideration when making his plans. He had with him a whistle of great power and shrillness, and did not fear any upsetting or misunderstanding of signals. The final reserve at the landing, of course, was nearly out of the whistle's range; hence would require a special messenger if needed for help. Moses Brown and John Carter went with Capt. Hopkins to the river-bank, while President Manning was detailed with Capt. Mathewson to the stone building. Dr. Bowen, with Ezra Weeden, remained in Capt. Whipple's party which was to storm the farmhouse itself. The attack was to begin as soon as a messenger from Capt. Hopkins had joined Capt. Whipple to notify him of the river party's readiness. The leader would then deliver the loud single blast, and the various advance parties would commence their simultaneous attack on three points. Shortly before 1 a .m. the three divisions left the Fenner farmhouse; one to guard the landing, another to seek the river valley and the hillside door, and the third to subdivide and attend to the actual buildings of the Curwen farm.
