The Blue and Yellow Brigades were posted among the vineyards on the road to Custrin; the White Brigade took post opposite one of the two gates of the town.

Hepburn and the Green Brigade were stationed opposite the other.
As the Swedes advanced the Imperialist garrison, who were 10,000 strong, opened fire with musketry and cannon from the walls.

The weakest point in the defence was assigned by Schomberg to Colonel Walter Butler, who commanded a regiment of Irish musketeers in the Imperialist service.
In the evening Hepburn and some other officers accompanied the king to reconnoitre near the walls.

A party of Imperialists, seeing some officers approaching, and judging by their waving plumes they were of importance, sallied quietly out of a postern gate unperceived and suddenly opened fire.

Lieutenant Munro, of Munro's regiment, was shot in the leg, and Count Teuffel, a colonel of the Life Guards, in the arm.
A body of Hepburn's regiment, under Major Sinclair, rushed forward and drove in the Imperialists, a lieutenant colonel and a captain being captured.
So hotly did they press the Imperialists that they were able to make a lodgment, on some high ground near the rampart, on which stood an old churchyard surrounded by a wall, and whence their fire could sweep the enemy's works.
