When the New Hampshire militia arrived, the grateful Colonel Prescott allowed Stark to deploy his men where he saw fit. Stark surveyed the ground and immediately saw that the British would probably try to flank the rebels by landing on the beach of the Mystic River, below and to the left of Bunker Hill. Stark led his men to the low ground between Mystic Beach and the hill and ordered them to "fortify" a two-rail fence by stuffing straw and grass between the rails. Stark also noticed an additional gap in the defense line and ordered Lieutenant Nathaniel Hutchins from his brother William's company and others to follow him down a bank to the edge of the Mystic River. They piled rocks across the beach to form a crude defense line. After this fortification was hastily constructed, Stark deployed his men three-deep behind the wall. A large contingent of British with the Royal Welch Fusiliers in the lead advanced towards the fortifications. The Minutemen crouched and waited until the advancing British were almost on top of them, and then stood up and fired as one. They unleashed a fierce and unexpected volley directly into the faces of the fusiliers, killing 90 in the blink of an eye and breaking their advance. The fusiliers retreated in panic. A charge of British infantry was next, climbing over their dead comrades to test Stark's line. This charge too was decimated by a withering fusillade by the Minutemen. A third charge was repulsed in a similar fashion, again with heavy losses to the British. The British officers wisely withdrew their men from that landing point and decided to land elsewhere, with the support of artillery.
