But, of course, his mind was intent on the work he had to do, and on the signals which would tell how the British were to proceed on their march to seize the rebel stores at Concord. The signals agreed upon were two lanterns if the troops went by way of water, one if they were to go by land. In Longfellow's story we learn that Newman---- "Through alley and street, Wanders and watches with eager ears, Till in the silence around him he hears The muster of men at the barrack door, The sound of arms and the tramp of feet, And the measured tread of the grenadiers, Marching down to their boats on the shore." It had been decided that the journey should be made by sea! The Province of Massachusetts, it must be understood, was at this time on the eve of open revolt. It had formed an army, commissioned its officers, and promulgated orders as if there were no such person as George III. It was collecting stores in anticipation of the moment when its army should take the field. It had, moreover, given General Gage--whom the king had sent to Boston to put down the rebellion there--to understand that the first movement made by the royal troops into the country would be considered as an act of hostility, and treated as such. Gage had up to this time hesitated to act. At length his resolution to strike a crippling blow, and, if possible, to do it without bloodshed, was taken. Spies had informed him that the patriots' depot of ammunition was at Concord, and he had determined to send a secret expedition to destroy those stores. Meanwhile, however, the patriots were in great doubt as to the time when the definite movement was to be made. Fully appreciating the importance of secrecy, General Gage quietly got ready eight hundred picked troops, which he meant to convey under cover of night across the West Bay, and to land on the Cambridge side, thus baffling the vigilance of the townspeople, and at the same time considerably shortening the distance his troops would have to march. So much pains were taken to keep the actual destination of these troops a profound secret, that even the officer who was selected for the command only received an order notifying him to hold himself in readiness. "The guards in the town were doubled," writes Mr. Drake, "and in order to intercept any couriers who might slip through them, at the proper moment mounted patrols were sent out on the roads leading to Concord. Having done what he could to prevent intelligence from reaching the country, and to keep the town quiet, the British general gave his orders for the embarkation; and at between ten and eleven of the night of April 18, the troops destined for this service were taken across the bay in boats to the Cambridge side of the river. At this hour, Gage's pickets were guarding the deserted roads leading into the country, and up to this moment no patriot courier had gone out." [Illustration: ROBERT NEWMAN HOUSE, BOSTON, MASS.]
