William and a tearful Mary were married in St. James's Palace by Bishop Henry Compton on 4 November 1677.[12] Mary accompanied her husband on a rough sea crossing back to the Netherlands later that month, after a delays of two weeks caused by bad weather.[13] Rotterdam was inaccessible because of ice, and they were forced to land at the small village of Ter Heijde, and walk through the frosty countryside until met by coaches to take them to Huis Honselaarsdijk.[14] On 14 December, they made a formal entry to The Hague in a grand procession.[15] Mary's animated and personable nature made her popular with the Dutch people, and her marriage to a Protestant prince was popular in Britain.[16] She became devoted to her husband, but he was often on campaign, which led to Mary's family supposing him to be cold and neglectful.[17] Within months of the marriage Mary was pregnant; however, on a visit to her husband at the fortified city of Breda, she suffered a miscarriage, which may have permanently impaired her ability to have children.[18] She suffered further bouts of illness that may have been miscarriages in mid-1678, early 1679, and early 1680.[19] Her childlessness would be the greatest source of unhappiness in her life.[20] From May 1684, the King's illegitimate son, James Scott, Duke of Monmouth, lived in the Netherlands, where he was fêted by William and Mary. Monmouth was viewed as a rival to the Duke of York, and as a potential Protestant heir who could supplant James in the line of succession. William, however, did not consider him a viable alternative and correctly assumed that Monmouth had insufficient support.[21]
