was becoming more intimate with his native Scottish subjects. David, however, spent several long periods resident in England. In fact, outside his "Cumbrian" principality and the southern fringe of Scotland-proper, David still exercised little power, and in the words of Richard Oram, was "king of Scots in little more than name". He was probably in the part of Scotland he did rule for most of the time between late 1127 and 1130, but was at the court of Henry in 1126 and early 1127, and returned to Henry's court in 1130 serving as a judge at Woodstock for the treason trial of Geoffrey de Clinton. It was in this year that David's wife, Matilda de Senlis, died. Possibly as a result of this, and while David was still in southern England, Scotland-proper rose up in arms against him. The instigator was his nephew Máel Coluim, who now had the support of Óengus of Moray, King or Mormaer of Moray. King Óengus was David's most powerful "vassal", a man who, as grandson of King Lulach of Scotland, even had his own claim to the kingdom. The rebel Scots had advanced into Angus when they were met by David's Mercian constable, Edward; a battle took place at Stracathro near Brechin. According to the Annals of Ulster, 1000 of Edward's army, and 4000 of Óengus' army, including Óengus himself, died. According to Orderic Vitalis, Edward followed up the killing of Óengus by marching north into Moray itself, which, in his words, "lacked a defender and lord"; and so Edward, "with God's help obtained the entire duchy of that extensive district". However, this was far from the end of it. Máel Coluim again escaped, and four years of this continuing Scottish "civil war" followed; for David this period was quite simply a "struggle for survival". It appears that David applied for and obtained extensive military aid from his patron, King Henry. Ailred of Rievaulx relates that at this point a large fleet and a large army of Norman knights, including Walter l'Espec, and were sent by Henry to Carlisle to assist in David's attempt to root out his Scottish enemies. The fleet seems to have been used in the Irish Sea, the Firth of Clyde and the entire Argyll coast, where Máel Coluim was probably at large among supporters. By 1134 Máel Coluim was captured and imprisoned in Roxburgh Castle. Pacification of the west
