Robert is generally accepted as responsible for strengthening the cult of Winifred, who had hitherto been an obscure Welsh saint, so that she became the focus of pilgrimages from Shrewsbury and other centres from the 14th century to the present. Later he became the fifth abbot and, although little is known of his abbacy, he seems to have been zealous in pursuing the abbey's interests against local rivals. He was successful in recovering two portions of the tithes of Emstrey parish church which had been granted "against conscience and the consent of his convent" by Abbot Ralph to the church at Atcham. Emstrey was a large parish, which stretched from the western bank of the River Severn opposite Atcham to the Abbey Foregate. The Abbey cartulary contains an instrument by which the Archbishop, Theobald of Bec, orders Bishop Walter to restore the tithes to the abbey. The underlying rivalry was not between the Shrewsbury Abbey and the little church of St Eata, but between the Shrewsbury and its Augustinian rival, Lilleshall Abbey which was tightening its grip on Atcham manor and parish, apparently to expand it across the Severn. Its ownership of the ferry crossing at Atcham was an important source of income for Lilleshall. It had recently acquired the advowson of Atcham church, and was later allowed to appropriate the church by Thomas Becket. By the beginning of the Plantagenet era Shrewsbury Abbey faced considerable competition for resources from major monasteries in the vicinity. As well as Lilleshall, technically a royal foundation, but effectively the creation of the brothers Philip and Richard de Belmeis II, there was Haughmond Abbey, another large Augustinian house closely connected with the FitzAlan family, and Buildwas Abbey, a large Cistercian house that received gifts from many of the local nobility, including the Belmeis and FitzAlans.
