Isaac was the captain of the Medford Minute Men; and when the storm of war which had been gathering broke at last, the men of Medford were among the first to respond and perform their share in the War for Independence. Paul Revere in his personal narrative tells how he had crossed the river, passing the British man-of-war Somerset; had mounted Deacon Larkin's horse and started on his ride, intending to pass over Charlestown Neck and over through Cambridge. Near what is now Sullivan Square he met two British officers who tried to stop him. He turned and pushed for the Medford road, and got clear of them. He says, ‘I went through Medford over the bridge and up to Menotomy. In Medford I waked the Captain of the Minute Men, and after that, I alarmed almost every house till I got to Lexington.’

Miss Helen T. Wild in her History of Medford in the Revolution says, ‘Captn Hall and his company marched to Lexington and there joined Captn John Brooks and his Reading company . . . . The combined companies met the British at Merriam's Corner and followed them to Charlestown Ferry, continuing their fire until the last of the troops had embarked.’ The Medford company was in the 37th Mass. Regiment, commanded by Col. Thos. Gardner. In the account of the Battle of Bunker Hill in his Siege of Boston, Frothingham says, ‘After the British landed, this regiment (Gardner's) was stationed in the road leading to Lechmere's Point, and late in the day was ordered to Charlestown. On arriving at Bunker Hill, General Putnam ordered part of it to assist in throwing up defences commenced at this place. One company (Harris') went to the rail fence. The greater part under the lead of their colonel on the third attack advanced towards the redoubt. On the way, Colonel Gardner was struck by a ball, which inflicted a mortal wound.’ The loss of the regiment in this battle was six killed, seven wounded.
