In page Eustace IV, Count of Boulogne:

"

Eustace died suddenly that same year, in mid-August 1153, struck down (so it was said) by the wrath of God while plundering church lands near Bury St Edmunds. Others believed that Eustace died simply of a broken heart.[1] The death of Eustace was hailed with general satisfaction as opening the possibility of a peaceful settlement between Stephen and his rival, the young Henry Plantagenet.[2] According to William of Newburgh, Stephen was "grieved beyond measure by the death of the son whom he hoped would succeed him; he pursued warlike preparations less vigorously, and listened more patiently than usual to the voices of those urging peace."[citation needed]
