At the start of the Civil War the area that would become known as the
Black Country in North-West Worcestershire and Birmingham was one of the few places in England that could produce the various military stores of which King Charles I was in dire need. As he had failed to secure the arsenals of
Portsmouth and
Hull, he did not possess any supply of swords, pikes, guns, shot; all these Worcestershire could and did provide. Shot came from
Stourbridge and from
Dudley cannon. The numerous small forges which then existed on every brook in the north of the County turned out successive supplies of sword blades and pike heads. It is said that among the many causes of anger Charles had against Birmingham was that one of the best sword makers of the day, a man named
Robert Porter, who lived and made his blades in Worcestershire but sold them in Birmingham, refused at any price to supply swords for "
that man of blood", or any of his adherents. However, the Royalists had among their adherents Colonel
Dud Dudley, who had invented a means of smelting iron by the use of coal, and who claimed he could turn out "all sorts of bar iron fit for making of muskets, carbines, and iron for great bolts", both more cheaply, more speedily and more excellent than could be done in any other way. His method was now employed on the King's behalf.
Clarendon adds that Birmingham was then: Rupert's mission was, therefore, threefold. Punish Birmingham, garrison Lichfield, and clear the country as far as possible. To do this he was given a force of 1200 horse and dragoons and 600 or 700 foot. Here the further approach to Birmingham was barred by some of the slight earthworks which had been thrown up. The men of Birmingham possessed a very inadequate force to defend these works. In the town a small company of foot soldiers under Captain Richard Greaves was stationed. The Lichfield garrison had sent in a troop of horse, but their united strength barely exceeded 200 men. Rupert did not believe that his large body would be opposed by so inferior a force. He therefore sent his Quarter-Master forward to take up his lodgings, and to ==Battle==
