The defeat of the Royalist army at the River Perch appeared comprehensive, Parliament's men had taken few casualties whilst the King's men had broken in their bid to force the Roundhead position. The immediate aftermath of the battle was something of a let off for the Royalists however, as their opponents failed to press the advantage and pursue the broken Cavaliers.
As the Royalist army fled the field the Parliamentarian commander and local dignitary Edward Dighurst was minded to order a general advance, and such a move would doubtless have led to yet more Royalist casualties, but it did not happen. Dighurst was dissuaded from pursing his enemies by the cautious and taciturn Scottish mercenary Alastair Begby. Begby had masterminded the Roundhead deployment at the crossing of the Perch, specifically it was he who had managed the movement of the artillery that had lent such strength to Dighurst's position. Not a man to gamble, Begby was reluctant to send the Parliamentarian horse across the river, despite the obvious disarray of the Royalist cavalry. To a professional like Begby, it was inexplicable that the King's men had attacked such a strong position and he feared that their retreat was a ruse and that the main body of a much larger Royalist force was waiting to strike once the Roundheads had abandoned the security of their position.
Of course, no such force existed. The Royalist commander on the day, Gareth Williams, had mounted an improvised offensive in a bid to surprise the defenders of Borchester. He had failed and lost the bulk of his horse, and their brave colonel Rufus Dancy, in the attempt. Parliament's failure to pursue had allowed the infantry,and what was left tof the cavalry to escape.
As the last days of winter gave way to spring Borchester was secure. At the beginning of March a letter arrived from the Earl of Essex commending the Borsetshire Parliamentarians on holding the town. Strategically Borsetshire was important to both sides, its proximity to the Welsh marches meaning that it lay astride the King's recruiting grounds in South Wales and his base at Oxford.
