General Thomas Gage, Commander of the British forces in America, and successor of Thomas Hutchinson as Governor of Massachusetts Bay, landed in Boston, May 13, 1774. Inspired by a hope that his administration might soften the feeling of resentment against the Mother Country, by annulling some of its causes, his reception on the 17th was dignified and cordial. He was greeted with cheers by the multitude, the firing of salutes in his honor, and a lavish banquet in Faneuil Hall.[30] A few weeks before he had assured his king that the Americans "will be lions while we are lambs; but if we take the resolute part they will prove very weak."[31]

His military force then in Boston was less than 4,000 men,[32] and consisted of the Fourth or King's Own; Fifth; Tenth; Seventeenth: 3 Companies of the Eighteenth; Twenty-second; Twenty-third; Thirty-eighth; Forty-third; Forty-fourth; Forty-seventh; Fifty-second; Fifty-ninth; Sixty-third; Sixty-fourth; six or eight Companies of Artillery; and six or eight Companies of Marines, numbering 460, under Major Pitcairn.[33]

Major Gen. Heath is the authority for the statement that the Provincial Congress appointed a committee to make inquiry into the state of operation of the British Army in Boston, and on the 20th of March, they reported that there were about 2,850 men distributed as follows: Boston Common, about 1,700; Fort Hill, 400; Boston Neck, 340; in Barracks at the Castle, about 330; King Street, 80; that they were erecting works at Boston Neck on both sides of the way, well constructed and well executed. The works were in forwardness and mounted with ten brass and two iron cannon. The old fortification at the entrance of the town was replaced and rendered much stronger by the addition of timber and earth to the parapet, and ten pieces of iron cannon were mounted on the old platform. A block house had been brought from Governor's Island and was being erected on the south side of the Neck.[34]

But a short time was required to show that in every political question Gen. Gage was loyal to his king. Accordingly throughout the Province the press, the pulpit, the expression of opinion in public meetings, while professing loyalty to the king personally, were extremely bitter against his representative in command.

Conventions were held in the various Counties of the Province, the earliest one being in Berkshire County, July 6, 1774, followed by the one in Worcester County, Aug. 9. Resolutions were passed at each, professing loyalty to the king, but remonstrating strongly against Parliament. It was left for the Middlesex County Convention, August 30, to pass resolutions that rang throughout the Province. While also professing loyalty to the King their final sentence was:

"No danger shall affright, no difficulties intimidate us; and if in support of our rights we are called to encounter even death, we are yet undaunted, sensible that he can never die too soon, who lays down his life in support of the laws and liberty of his country."

These resolutions were passed by a vote of 146 yeas against 4 nays.[35]

Although the town of Boston itself was the headquarters of Gen. Gage, and his soldiers were parading in its streets, and encamping on its Common, the patriots had by no means deserted it. There were several secret societies who made it their business to watch for and report hostile movements and plans. These were the "North End Caucus;" the "South End Caucus;" the "Middle District Caucus;" and the "Long Room Club;" all of which owned allegiance to the "Sons of Liberty," a body which acted in the capacity of a higher council and which kept itself in close communication with similar organizations outside of this Province. Members of these various bodies paraded the streets nightly, that any sudden or unusual movement of the army might be at once reported. Paul Revere belonged to one or more of these, and was active in patriotic work.

Nor was Gen. Gage idle in acquiring information about the Provincial Army being assembled, and the topographical features of the country around Boston. His troops were especially trained by marches, over the highways in the vicinity,[36] and his spies brought him maps and reports from the scenes of his possible future operations. The two that acted for him in this secret service were Capt. Brown of the 52nd regiment, and Ensign De Bernicre of the 10th regiment. They were disguised in "brown clothes" with "reddish handkerchiefs" tied about their necks, and were accompanied by a servant. All three were well armed.

Gen. Gage's instructions to them, under date of Feb. 22, 1775, called for description of the roads, rivers, and hills; available places for encampments; whether or not the churches and church yards were advantageous spots to take post in and capable of being made defensible. They were also told that information would be useful in reference to the provisions, forage, etc., that could be obtained at the several places they should pass through.

Their first trip was to Worcester, in the latter part of February, and their next one to Concord, for which place they set out on March 20, passing through Roxbury, Brookline, and Weston, where they stopped at the Jones Tavern.

Then they proceeded through Sudbury, crossed over the South Bridge into Concord village, where they were entertained by a Mr. Bliss, a friend of the royal government.

Wherever they went their mission was known in spite of their disguises. They succeeded, however, in bringing back to Gen. Gage a very tolerable description of the country, and so fulfilled their mission. In Concord, especially, they located many of the provincial military stores, information particularly useful to the invading force on April 19th.

Having thus possessed himself of sufficient data, Gen. Gage then laid his plans for a midnight march to Lexington and Concord with the view, possibly, of capturing Hancock and Adams, who were known to be at the former place, and especially of destroying all the war-like supplies that had been gathered at Concord.

April 15, the grenadiers and light infantry had been relieved from duty, with the excuse that they were to learn a new exercise. That night, about twelve o'clock, boats belonging to the transports which had been hauled up for repairs were launched and moored under the sterns of the men-o-war.[37] The Somerset was anchored near the Charlestown Ferry.[38] These movements awakened the suspicions of Dr. Warren, who lost no time in notifying Hancock and Adams, then at Lexington. On the afternoon of April 18th, he learned from several sources that the British were about to move. A gunsmith named Jasper, learned as much from a British sergeant and lost no time in informing Col. Waters of the Committee of Safety, who in turn gave the news to Warren.[39] John Ballard, connected with the stable in Milk Street, overheard some one in the Province House remark that there would "be hell to pay tomorrow;" a remark so full of significance that he reported it to a friend of liberty in Ann Street, thought to have been William Dawes, who in turn reported it to Paul Revere.[40]

That night Gen. Gage despatched ten or more sergeants, partially disguised, along the highways in Cambridge and beyond, towards Concord. They were instructed to intercept any passers-by, and so prevent his intended movement from becoming known. A party of his officers dined at Wetherby's Tavern[41] in Menotomy (now Arlington), where also met that day the Committee of Safety and Committee of Supplies, some of whom, Mr. Gerry, Col. Orne and Col. Lee, remained to pass the night.[42]
