1335-6: "...AND FALL AGAIN, AND RISE AGAIN, TO FIGHT ON ANEW..."
"The planned joint attack on the Bruce loyalists was an ambitious design, one that bears all the marks of Edward Balliol's simultaneously keen and fervent military mind. The Anglo-Galloway forces were to split in two, with one force under the Prince's leadership would start from Carlisle, and march north, while a second force under Balliol's leadership would march west from Berwick. The two armies were to meet at Clyde, where they would be joined by a third force recruited from Ireland[1].
"Such at least was the plan, though they instead met at Glasgow, and the third army never materialized that year due to recruitment problems in Ireland. Not that it would have served much purpose, as the two forces never fought a pitched battle. Instead, they proceeded virtually unimpeded through Scottish territory, looting and spreading terror. The Earls of Stafford and Gloucester both reportedly declared it the most pointless campaign they had ever fought in during their long military careers--arguably quite a just verdict. For all the terror the English would spread throughout the fall of 1335, and into 1336, it did very little to defeat the Scots.
"That honor would go to the Scots themselves. The dual Guardianship of Moray and Stewart was a highly unusual form of government which would have required great diplomatic skill to keep afloat. As they were a pair of impetuous youths (especially Stewart), this was not something in high supply. Thus, even as the English looted, the two Guardians feuded with each other, each working to seize as much royal income as possible while accusing the other of banditry. Moray was caught during a raid in late July, while Stewart had by this time made himself so odious to any but his nearest partisans that as Froissart put it 'his word was naught beyond his own lands, and even then only those of them that he held'. This left the perennially opportunistic Earl of Atholl as de facto leader of the Scottish rebels, and Atholl swiftly reverted to type, contacting his father-in-law to make peace, and bringing a dozen or so Scottish nobles with him[2]. Once again, the Scottish cause seemed all but lost. And once again it revived.
"A meeting of the battered remnants of Bruce loyalists in Dumbarton--save for Stewart, who was either not invited or refused to come--chose a new Guardian, Sir Andrew Murray, who had held the title previously, before being captured by the English. As opposed to many in his situation, Sir Andrew, who was the late King Robert's brother-in-law[3], had never submitted to Balliol and the Prince of Wales, even in captivity. Despite this, Sir Andrew had been allowed to ransom himself, a move the young Prince would come to greatly regret[4]...
"Murray started by offering the Prince a truce. Facing diminishing resources, an increasing spectre of French involvement, and a conflict that was beginning to resemble a morass, the Prince took it, even though it left his brother-in-law and his supporters to hang by themselves. It also did nothing to restrain John Stewart, who still sulkily did not regard Sir Andrew Murray as the true Guardian of Scotland. Balliol seems to have paid little regard to the former matter and a great deal to the latter. Most likely, he considered the rebels on their last legs, and saw their refusal to deal with him at the moment as a face-saving device, while seeing Stewart as 'a wolf on two legs' whose disposal would not only strengthen his own cause, but win him general praise.
"Unfortunately for Balliol, once again internal divisions returned to plague his followers in light of victory. With Stewart a rebel and outlaw by the Balliol line, a new Great Steward was needed--Balliol selected the Earl of Mar, likely under pressure from Prince Edward, who saw Mar as reliable and trustworthy[5]. Unfortunately, this offended the Earl of Atholl, who had hoped to gain the position himself, despite his opportunistic past. While the extent of his disenchantment remains unknown, it was at the very least exceedingly demoralizing for Atholl, and did nothing to shore up his always uncertain loyalties. Being placed under Mar as the latter was sent out to 'bring the rebel John of Lauder[6] to heel', likewise did little to help...
"Despite the claims of Mar and Atholl, the campaign against Stewart served as little more than an excuse to murder, loot and intimidate Bruce loyalists in the region. Eventually the pair's efforts brought them to Kildrummy Castle--Sir Andrew's own home, presently under the care of his formidable wife, Christina Bruce[7]. That redoubtable lady took up the castle's defense and succeeded in holding Mar and Atholl off. Murray's response to the siege was to break off the peace talks and race to Kildrummy's rescue. After some debate, Mar left the siege in Atholl's hands and rushed off to face Murray's small force. The resulting clash at the River Dee ended in Mar's utter defeat--his men were scattered, and the Earl killed fighting beneath an oak tree[8]. Atholl's response to this was to break off the siege and take his wife and family to the island fortress of Lochindorb[9], where he would spend the next year alternating between calling Balliol and the English for help and offering to surrender to the Scots.
"In Galloway, Balliol and his queen were left in the great ruin of Roxburgh, which Prince Edward had begun to repair only to abruptly stop. The half-repaired ruin was in many ways the perfect symbol of his Scottish war, left off incomplete even as it was begun as the Prince found himself preoccupied with other matters..."

[1] Balliol reportedly assisted Edward's plans IOTL, though this author is exaggerating his contribution.
[2] Moray and Robert Stewart's OTL uprising collapsed in a similar manner, though Robert had the sense to surrender when things had definitively turned against him.
[3] Sir Andrew's marriage to Robert Bruce's sister Christina is quite interesting. He was her second husband--many accounts have her twenty years older than him, with the result that Sir Andrew's children are frequently credited to an unknown first wife. However, given certain other inconsistencies in accounts of Christina, among them a phantom third marriage that proceeded the other two which her contemporaries don't seem to be aware of, it is most likely that there were two Bruce sisters of that name, and Sir Andrew married the younger one, thus making his mysterious first wife nothing more than an error of modern chroniclers.
[4] Murray was likewise ransomed by Edward IOTL. It was a mistake, and one Edward learned not to repeat.
[5] IOTL, Atholl was named Steward, Balliol not having a dearth of reliable followers.
[6] Stewart's father was also known as Walter of Lauder.
[7] Christina likewise defended her husband's castle IOTL, not the only woman who would do this in this era.
[8] IOTL, it was Atholl who perished beneath the oak tree.
[9] IOTL, Lochindorb served as a refuge for Atholl's wife and her retinue.
