The investment began in the evening, but so vigorously did the Scotch work all night in spite of the heavy musketry and artillery fire with which the garrison swept the ground that by morning the first parallel was completed, and the soldiers were under shelter behind a thick bank of earth.
All day the Imperialists kept up their fire, the Scots gradually pushing forward their trenches.

In the evening Colonel Axel Lily, one of the bravest of the Swedish officers, came into the trenches to pay a visit to Hepburn.

He found him just sitting down to dinner with Munro by the side of a fire in the trench.

They invited him to join them, and the party were chatting gaily when a heavy cannonball crashed through the earthen rampart behind them, and, passing between Hepburn and Munro, carried off the leg of the Swedish officer.
Upon the following day the governor, seeing that the Swedes had erected several strong batteries, and that the Green Brigade, whose name was a terror to the Imperialists, was preparing to storm, capitulated, and his soldiers were allowed to march out with all their baggage, flying colours, and two pieces of cannon.

Eighty pieces of cannon fell into the hands of the Swedes.
