After staying for a period in Robert's stronghold of Bristol, Matilda established her court in nearby Gloucester, still safely in the south-west but far enough away for her to remain independent of her half-brother. Although there had been only a few new defections to her cause, Matilda still controlled a compact block of territory stretching out from Gloucester and Bristol south into Wiltshire, west into the Welsh Marches and east through the Thames Valley as far as Oxford and Wallingford, threatening London. Her influence extended down into Devon and Cornwall, and north through Herefordshire, but her authority in these areas remained limited.
