but most did not. The cavalry were divided into four battalions, each consisting of 15–20 bannerets (60–80 total), each in command of on average 13 knights and squires (780–1,040 total). Edward also requested 16,000 infantry from his magnates, but was only able to muster 9,000 infantry, giving his army a total count of around 10,000. The infantry were grouped into units of 100, each commanded by an armoured serjeant, which were further subdivided into units of 20. The average daily rate of pay was 2d (two pence) for a spearman or billman, 12d (one shilling) for a serjeant, 24d (two shillings) for a knight, 6d for a hobelar, 6d for a mounted archer, 4-6d for a crossbowman, and 3d for a foot archer. With the success of the English at Falkirk two years earlier, Edward must have felt in a position to bring Scotland under full control permanently. To do this required further campaigning, eliminating the last opposition and securing castles that were (or would be) centres of resistance. The English took control of Caerlaverock Castle, but apart from some small skirmishes, there was no action. In August, the Pope sent a letter demanding that Edward withdraw from Scotland. Due to the lack of success, Edward arranged a truce with the Scots on 30 October and returned to England. That year, Robert Bruce finally resigned as joint guardian and was replaced by Ingram de Umfraville. In May 1301, de Umfraville, John Comyn and William Lamberton resigned as joint guardians and were replaced by John de Soulis as sole guardian. Soulis was appointed largely because he was not part of either the Bruce or the Comyn camps, and was a patriot. He was an active guardian, and made renewed efforts to have John Balliol returned to the Scottish throne. In July 1301, Edward launched his sixth campaign into Scotland, aiming to conquer Scotland in a two-pronged attack. One army was commanded by his son, Edward, Prince of Wales, the other, the larger, was under his own command. The prince was to take the southwestern lands and the greater glory, so his father hoped. But the prince held cautiously to the Solway coast. Scot forces, commanded by de Soulis and de Umfraville, attacked the prince's army at Lochmaben in early September and maintained contact with his army as it captured Robert the Bruce's Turnberry Castle. They also threatened the king's army at
