In the evening of 5 August 1549, during the
Prayer Book Rebellion,
John Russell, 1st Earl of Bedford and
Lord William Grey and their troops had pitched camp on Clyst Heath. Russell and Grey were concerned about the burden of the large number of rebel prisoners that had been captured from previous encounters at Fenny Bridges,
Woodbury Common and
Clyst St Mary. An order was issued that the prisoners should be killed, which was done. According to
John Hayward, more than nine hundred prisoners were slain. The following day the rebels attacked the camp of the Royal army and the subsequent battle lasted the entire day, with heavy losses on both sides. Lord Russell's troops were finally victorious, but
John Hooker later reported:Great was the slaughter and cruel was the fight and such was the valour and stoutness of these men [the rebels] that the Lord Grey reported himself that he never in all the wars he had been did know the like. ==See also==
