The battle was a major encounter in James's attempt to regain the thrones of England and Scotland, resulting from the
Invitation to William and William's wife, Mary, from the 'immortal seven' English peers to take the throne to defend Protestantism. But the conflict had broader and deeper European geopolitical roots, of the League of Augsburg and the
Grand Alliance against the expansionist ambitions of Catholic
Louis XIV of France, or of the
House of Bourbon against the
House of Habsburg. If the battle is seen as part of the
War of the Grand Alliance,
Pope Alexander VIII was an ally of William and a friend to James; the
Papal States were part of the Grand Alliance with a shared hostility to the Catholic Louis XIV of France, who at the time was attempting to establish dominance in Europe and to whom James was an ally. The previous year William had sent the
Duke of Schomberg to take charge of the Irish campaign. He was a 74-year-old professional soldier who had accompanied William during the
Glorious Revolution. He brought an army of 20,000 men, which arrived at
Bangor. Under his command, affairs had remained static and very little had been accomplished, partly because the English troops suffered severely from fever and the army's move south was blocked by Jacobite forces; both sides camped for the winter. To these ends, under
Richard Talbot, 1st Earl of Tyrconnel, they had raised an army to restore James II after the Glorious Revolution.
Sir James Fitz Edmond Cotter being the commander-in-chief of all
King James's forces in the counties of Cork, Kerry, Limerick, and Tipperary. By 1690, they controlled all of Ireland except for
Derry and
Enniskillen. Conversely, for the Williamites in Ireland, the war was about maintaining Protestant rule in Ireland. They feared for their lives and their property if James and his Catholic supporters were to rule Ireland, nor did they trust the promise of tolerance, seeing the Declaration of Indulgence as a ploy to re-establish Catholicism as the sole
state religion. James had already antagonised English Protestants with his actions. In particular, they dreaded a repeat of the
Irish Rebellion of 1641, which had been marked by widespread killing. For these reasons, Protestants fought
en masse for William of Orange. Many Williamite troops at the Boyne, including their very effective irregular cavalry, were
Ulster Protestants, who called themselves "
Enniskilliners" and were referred to by contemporaries as "
Scots-Irish". These "Enniskilliners" were mostly the descendants of Anglo-Scottish
border reivers; large numbers of these reivers had settled around Enniskillen in
County Fermanagh.
Commanders The opposing armies in the battle were led by the Roman Catholic king James II of England and Ireland (VII of Scotland) and, opposing him, his nephew and son-in-law, the Protestant king William III ("William of Orange") who had deposed James the previous year. James's supporters controlled much of Ireland and the Irish Parliament. James also enjoyed the support of his cousin, Louis XIV, who did not want to see a hostile monarch on the throne of England. Louis sent 6,000 French troops to Ireland to support the Irish Jacobites. William was already
Stadtholder of the Netherlands and was able to call on Dutch and allied troops from Europe as well as
England and
Scotland. However, recent historians have suggested that he was prone to panicking under pressure and making rash decisions, which it has been suggested may have been due to poor health associated with the Stuart line. William, although a seasoned commander, had yet to win a major battle. William's success against the French had been reliant upon tactical manoeuvres and good diplomacy rather than force. a multi-national coalition formed to resist French aggression in Europe. From William's point of view, his taking power in England and the ensuing campaign in Ireland was just another front in the war against France in general, and Louis XIV in particular. James II's subordinate commanders were
Richard Talbot, 1st Earl of Tyrconnell, who was
Lord Deputy of Ireland and James's most powerful supporter in Ireland;
Sir James Fitz Edmond Cotter, Brigadier General in command of all the Jacobite forces in counties Cork, Kerry, Limerick and Tipperary, and an intimate of
James II; and the French general
Lauzun. William's commander-in-chief was the Duke of Schomberg. Born in
Heidelberg, Germany, Schomberg had fought for a few different countries and had formerly been a
Marshal of France, but, being a
Huguenot, was compelled to leave France in 1685 because of the
revocation of the Edict of Nantes.
Armies The
Williamite army at the Boyne was about 36,000 strong, composed of troops from many countries; Only around half of them were British. Around 20,000 troops had been in Ireland since 1689, commanded by Schomberg.
Loughbrickland was the rallying point of the scattered divisions of the army. He arrived there with another 16,000 in June 1690. On 30 June O.S. William had reached the top of a hill near the southern border of County Louth. The Danish infantry was commanded by General
Ernst von Tettau. There was also a large (3000) contingent of French Huguenot troops fighting with the Williamites. However, this battle would give William cause to evaluate them more favourably, due to the impressive behaviour of the English troops, such as the Duke of Beaufort's Regiment of Foot. James’s flag was erected at the town of
Donore, on the opposite side of the river Boyne. However, the Irish infantry, predominantly
peasants who had been pressed into service, were not trained soldiers. They had been hastily trained, poorly equipped, and only a minority of them had functional muskets. In fact, some of them carried only farm implements such as
scythes at the Boyne. Furthermore, the Jacobite infantry who actually had firearms were all equipped with the obsolete
matchlock musket. The French and Irish troops wore a white rallying mark, as a compliment to the Bourbons and to distinguish them from the Williamites. ==Battle==
