The Battle of Old Byland (also known as the Battle of Byland Moor and Battle of Byland Abbey) was a significant encounter between Scots and English troops in Yorkshire in October 1322, forming part of the Wars of Scottish Independence. It was a victory for the Scots, the most significant since Bannockburn, though on a far smaller scale.
Ever since Robert Bruce's victory at the Battle of Bannockburn in 1314, the Scots had taken the initiative in the wars with England, raiding deep into the north of the country repeatedly and with comparative ease to attempt to force the English to the peace-table. The English king, Edward II seemed incapable of dealing with the problem, distracted, as he often was, in a political struggle with his own barons and refused to even begin peace negotiations with the Scots which would have required recognizing Robert the Bruce as King of the Scots. In early 1322 the situation had become critical, with some senior English noblemen, headed by Thomas of Lancaster, preparing to enter into an alliance with the Scots.
