John Sassamon.
Betty's Neck.

There was at this time a Christian Indian by the name of John Sassamon, who had learned to read and write, and had become quite an efficient agent in Christian missions to the Indians. He was esteemed by the English as truly a pious man, and had been employed in aiding to translate the Bible into the Indian language, and also in preaching to his countrymen at Nemasket, now Middleborough. He lived in semi-civilized style upon Assawompset Neck. He had a very pretty daughter, whom he called Assowetough, but whose sonorous name the young Puritans did not improve by changing it into Betty. The noted place in Middleborough now called Betty's Neck is immortalized by the charms of Assowetough. This Indian maiden married a warrior of her tribe, who was also in the employment of the English, and in all his interests had become identified with them. Sassamon was a subject of King Philip, but he and his family were on the most intimate and friendly relations with the colonists.

Private secretary of Philip.
The conspiracy.
Incredulity of the English.

Philip needed a private secretary who could draw up his deeds and write his letters. He accordingly took John Sassamon into his employment. Sassamon, thus introduced into the court and cabinet of his sovereign, soon became acquainted with the conspiracy in all its appalling extent and magnitude of design. He at once repaired to Plymouth, and communicated his discovery to the governor. He, however, enjoined the strictest secrecy respecting his communication, assuring the governor that, should the Indians learn that he had betrayed them, his life would be the inevitable forfeit. There were many who had no faith in any conspiracy of the kind. Rumors of approaching perils had been rife for many years, and the community had become accustomed to them. Most of the Massachusetts colonists thought the Plymouth people unnecessarily alarmed. They listened to the story of Sassamon with great incredulity. "His information," says Dr. I. Mather, "because it had an Indian original, and one can hardly believe them when they do speak the truth, was not at first much regarded."

Sassamon soon after resigned his situation as Philip's secretary, and returned to Middleborough, where he resumed his employment as a preacher to the Indians and teacher of a school.

Sassamon to be murdered.

By some unknown means Philip ascertained that he had been betrayed by Sassamon. According to the Indian code, the offender was deemed a traitor and a renegade, and was doomed to death; and it was the duty of every subject of King Philip to kill him whenever and wherever he could be found. But Sassamon had been so much with the English, and had been for years so intimately connected with them as their friend and agent, that it was feared that they would espouse his cause, and endeavor to avenge his death. It was, therefore, thought best that Indian justice should be secretly executed.

Death of Sassamon.
Indians arrested.

Early in the spring of 1675 Sassamon was suddenly missing. At length his hat and gun were found upon the ice of Assawompset Pond, near a hole. Soon after his body was found beneath the ice. There had been an evident endeavor to leave the impression that he had committed suicide; but wounds upon his body conclusively showed that he had been murdered. The English promptly decided that this was a crime which came under the cognizance of their laws. Three Indians were arrested under suspicion of being his murderers. These Indians were all men of note, connected with the council of Philip. An Indian testified that he happened to be upon a distant hill, and saw the murder committed. For some time he had concealed the knowledge thus obtained, but at length was induced to disclose the crime. The evidence against Tobias, one of the three, is thus stated by Dr. Increase Mather:
