It was these three lords who in 1310 led an attack in Parliament on the king and his favourite, and drew up a scheme for taking the direct rule of the realm out of their hands. Following the precedent of the Provisions of Oxford,[21] the Parliament named a committee of regency, or body of ministers, composed of twenty-one members, who were called the Lords Ordainers, and were to draw up a scheme for the reform of all the abuses of the kingdom. The twenty-one comprised the Archbishop of Canterbury and all the leading men of England, but Thomas of Lancaster and his friends had the ascendency among them. The king complained that he was treated like a lunatic, and deprived of the right that every man owns, of being allowed to manage his own household. He resolved by way of protest, to show that he could do something useful, and, taking Gaveston with him, made an incursion into Scotland. Bruce was cautious, and retired northward, burning the country behind him. The king struggled on as far as the Forth, and then turned back without having accomplished anything. On his return he was forced to sign a promise to redress many administrative grievances which the Lords Ordainers laid before him--to consent to banish Gaveston, choose all his ministers with the counsel and consent of his baronage, disallow all customs and taxes save such as Parliament should grant, and reform the administration of justice. Edward signed everything readily, but immediately departed into the north, bade Gaveston return to England and join him, and published a repudiation of the new ordinances, as forced on him by threats and violence (1311). [Sidenote: =Murder of Gaveston.=] This contumacy brought matters to a head. Lancaster and his friends took arms and laid siege to Scarborough, where the favourite lay. Gaveston surrendered on a promise that he should have a fair trial in Parliament. But while he was being taken southward, the Earl of Warwick came upon his keepers, drove them away, and took Piers out of their hands. Without trial or form of justice, "The Black Dog of Arden" bade his retainers behead the favourite by the wayside on Blacklow Hill (May, 1312). Thomas of Lancaster approved by his presence this gross and faithless violation of the terms on which Gaveston had surrendered at Scarborough. [Sidenote: =Progress of Bruce.=]
