The prelude to this dramatic performance was pronounced in the Massachusetts Assembly, one day in June, 1773, by Mr. John Hancock, who darkly declared that within eight and forty hours a discovery of great pith and moment would be made to the House. On the next day but one, Samuel Adams arose and desired the galleries cleared, as there were matters to lay before the members which the members only had a right to know of. When the galleries were cleared he informed the House that certain letters, written by high officials in the province and extremely hostile to the rights and liberties of America, had been procured in England and transmitted to a gentleman who had in turn placed them in his, Mr. Adams's, hands, but with the strictest injunction that they be returned without being copied or printed. Mr. Adams had given his pledge to this effect; and, if the House would receive them on these terms, he would be glad to read the letters, no restriction having been placed on their being read. They were read accordingly; and a committee having been appointed to make recommendations, it was at length resolved by the House of Assembly that certain letters presented to it by Mr. Samuel Adams tended and were manifestly designed to undermine the Constitution and establish a despotic power in the province. The proceedings of the House being spread abroad, it soon became everywhere known that only the pledged word of the House stood in the way of revelations highly damaging to the public character of Governor Hutchinson.
This outcome of the matter, however gratifying to Samuel Adams, did not satisfy Governor Hutchinson. After there had been "buzzed about for three or four months a story of something that would amaze everybody," and these dark rumors being "spread through all the towns in the province and everybody's expectations ... raised," it was exasperating to his pragmatic nature to have nothing more definite transpire than that the something which would amaze everybody would indeed amaze everybody if only it could be made known. It should at least be made known to the person most concerned. The Governor therefore requested the Assembly to furnish him copies of the letters which were attributed to him and declared by the House to be destructive of the Constitution. In reply, the House sent certain dates only. The House was of opinion that the Governor could easily make authentic copies of whatever letters he had written at these dates, if he had written any; and such copies, being furnished to the Assembly, might be published, and the whole matter thus cleared up without violating the pledged word of anyone.
