Lacking a guide, the English army decided to march back to Carmarthen. The Welsh armies in the woods hit the English with devastating guerrilla attacks (using mostly bows or javelins) from the first hour of Saturday right up until midday. There was an engagement between the two forces at midday which saw the Welsh troops outflank the English and successfully capture the English supply train at Coed Llathen. Although there seem to have been few casualties, the engagement at Coed Llathen swung the balance in favour of the Welsh since the English had lost most of their provisions.
