On the previous day, Sunday, which was the day after that of the arrival of Dick and Tom, a vessel had taken some British troops to Grape Island, in Boston Harbor, to get the hay there stored. An alarm of bells and guns had brought out the people of Weymouth, Hingham, and other towns, and they had landed on the island with three companies sent by General Thomas from Roxbury, driven the British away, burnt the hay, and taken off a number of cattle. This un-Sabbath-like exploit was the talk of the camp on Monday, and Dick deplored his not having heard of it in time to have sought a part in it.

Captain Maxwell's men proved excellent hosts, and, though not on its rolls, Dick and Tom shared the company's service and experiences in every way. Colonel Prescott's regiment was soon ordered to Cambridge, where was stationed the centre of the New England army, consisting of fifteen Massachusetts and several Connecticut regiments, one of the latter being General Putnam's. Here were the headquarters of General Ward, the commander-in-chief, in a fine wooden residence near Harvard College, and here was Colonel Gridley, the chief engineer, with most of the artillery. Here were also most of the Yankees' fortifications, these being yet in process of construction, and consisting mainly of breastworks in Cambridge and on the road near the base of Prospect Hill. Further north and northeast was the army's left wing, consisting mainly of Colonels Stark's and Reed's New Hampshire regiments, and stationed at Medford, Chelsea, and near Charlestown Neck.

It was the lot of Dick and MacAlister, as participants in the fortunes of Maxwell's company, to occupy part of a log hut near Cambridge Common and in sight of the college, and to have no share in the enterprises of May 27th and 30th, in which American detachments went to Noddle's Island, near Chelsea, and drove off sheep, cattle, and horses, on the first occasion killing and wounding several British marines and capturing twelve swivels and four four-pounders from a British schooner. There was a skilful removal of sheep and cattle from Pettick's Island also, on May 31st; and on the night of June 2d Major Greaton took from Deer Island eight hundred sheep and a lot of cattle, and captured a man-of-war's barge and four or five prisoners. Dick pined and chafed that circumstance kept him out of all these interesting proceedings, but Tom the Fiddler (a name promptly bestowed on him by Prescott's men) consoled him with many a "Whist, man, bide a wee; there'll be bigger business a-brewing!"

So Dick bided, with eager anticipations, although, in his inexperience, heeding the grumbling of others, he thought the conviviality between certain American and British officers on the man-of-war Lively, on the occasion of an exchange of prisoners, June 6th, did not look much like war. He was better pleased at the derision with which the raw troops received General Gage's proclamation of June 12th, which somehow promptly found its way into camp. In that document the British commander pronounced those in arms and their abettors to be rebels and traitors, and offered pardon to such as should lay down their arms, excepting Samuel Adams and John Hancock. Continually there came exciting rumors that the British intended to sally out of Boston to attack their besiegers. But Dick did not know what the American commanders knew, on June 13th,—that General Gage intended to take possession of Dorchester Heights on the 18th; hence it was with surprise and a keen thrill that, on Friday evening, the 16th, he obeyed the order to fall in, and marched beside MacAlister with the company to Cambridge Common.

There he found that Maxwell's men were part of a detachment which included other companies of Prescott's regiment, a part of Bridge's, a part of Frye's, and a number of Connecticut troops under Captain Knowlton, of Putnam's regiment. There was also some artillery, with Colonel Gridley himself. And there stood the tall, powerful figure of Colonel Prescott, wearing a long blue coat, his strong, stern face shaded by the slightly turned up brim of a great round hat. The air was charged with expectation, with a sense of great events at hand. The force paraded on the Common, and then stood with heads bared and hands resting on the guns, while a venerable-looking gentleman, whom a whispering comrade named to Dick as President Langdon of Harvard College, raised his hand heavenward and uttered a tremulous prayer for the aid of the Lord of Hosts. There was a period of waiting, during which the colonel consulted quietly with Gridley and the other officers, while the suppressed excitement of the men made some appear moody and abstracted, some nervous and sharp in their whispered speeches, others extraordinarily calm in tone, others oddly jocular. Dick was one of the last, in mood and countenance, but was so filled with emotion that he dared not trust himself to speak. Tom was placidly grim and patient, keeping his wits about him and exhibiting no change in tone or manner. The fallen darkness gave the human figures, the distant trees and scattered houses, the rolling landscape, a mysterious look. At last, at nine o'clock, in low, quick tone, the order was given to march.

First went two sergeants, carrying dark lanterns; then strode Colonel Prescott, at the head of the detachment. Behind the infantry and the cannon, the shovels and other tools were borne, with which to make entrenchments. Keeping strict silence, as they had been ordered, the men trailed past Inman's Woods, Prospect Hill, and Cobble Hill, crossed a level space (another common), and halted at Charlestown Neck. Here, in the darkness, General Putnam rode up, and they were joined by other officers also.

Presently Captain Nutting's company and a few Connecticut men separated from the detachment and marched to the lower part of Charlestown, to act there as a guard. The main force was soon on the march again, and followed the road over a smooth round hill (the real Bunker's Hill), at the base of which it halted again. Prescott gathered the officers around him, and quietly made known the orders he had come to carry out. Watching the group alertly, Dick saw the officers look or point, now at the hill just crossed, now at the hill ahead, as if discussing which to use for the purpose in hand. Finally the men were marched to the hill ahead, from which Boston on its hills and hillsides could be seen sleeping, across the wide mouth of the Charles River.

As soon as the men halted, Colonel Gridley began to move rapidly about the summit of the hill, marking out lines and angles in the earth as he did so. Guns were stacked by all but certain designated men, of whom Dick and Tom were two, who remained under arms. Spades were distributed to the others, who were soon turning up the earth along the lines traced by Colonel Gridley. As General Putnam started to ride back over the road they had followed, Captain Maxwell received an order from Colonel Prescott, and in turn gave the word of march to a party of his men, in which were numbered Dick and Tom.

This little force followed the captain down into Charlestown, whose commodious houses among the trees were now deserted. When the party neared the Old Ferry, which led to Boston, the men were assigned to different posts along the shore, to watch the motions of the enemy, on their men-of-war in the river and in Boston opposite, during the night. With what delicious feelings did Dick pace the shore, to the sound of the lapping water, in sight of the dark looming vessels of the foe, in hearing of the British sentinel's voice who passed the "All's well" on to his comrade! Twice during the night Colonel Prescott came down with another officer to see what might be seen from the shore. It was almost dawn when Tom and Dick were marched back to the hill, where the men had been doing beaver work in the night.

A great change had been made in the appearance of the hill. Mounds of earth six feet high now enclosed the crest on three sides and most of the fourth. A rough breastwork had been thrown up as if in continuation of one of the sides of this redoubt. On the inner side of these works rough platforms of wood and earth were being made, and Dick and Tom were now assigned to aid in this duty, the rule of the night having been that men should dig and mount guard alternately. Dawn came, calm and clear, while the men were working at the spades. As both mounted a pile of earth, to level it, Dick took the opportunity to look down over the parapet, towards Boston. At that instant there came a flash of fire and a belch of smoke from the port-hole of a vessel in the river, a sullen boom, and a spattering of earth and dust in the near hillside.
