Transcript
- Lucas: So, today we're picking up the story of the Williamite War in Ireland — specifically the Battle of the Boyne, fought in July 1690. We've touched on it before in episode 108, but I think it's worth going deeper, because this battle has become one of those events that's more symbol than history for a lot of people. Luna: The Twelfth of July parades, orange sashes, King Billy on a white horse — that's the image that comes to mind. Lucas: Exactly. But the real battle was a lot messier and more complex than the mural version. First, a quick refresher: in 1688, the Catholic James II was deposed in the Glorious Revolution and replaced by his Protestant daughter Mary and her husband William of Orange. James fled to France, then in 1689 landed in Ireland with French support, hoping to use it as a base to reclaim his throne. By 1690, William had come to confront him. Lucas: The two armies met on the banks of the River Boyne, near Drogheda, on July 1st by the old Julian calendar — July 12th under our modern Gregorian calendar, which is why Orangemen march on the Twelfth. William had about 36,000 men, a mix of English, Dutch, Danish, and Ulster Protestant troops. James had around 25,000, mostly Irish Catholics but with a contingent of French regulars under Lauzun. Luna: That's a significant size difference, but not overwhelming. Lucas: Right, and the Boyne itself was a natural obstacle — it's not a huge river, but it was deep enough in places to force the attackers to cross at specific fords. William scouted the river on the 30th of June and actually got wounded by a grazing cannonball — a Jacobite sniper nearly ended the whole campaign before it began. Luna: Wait, he was hit? Lucas: Yeah, a cannonball fired from the Jacobite lines struck him on the shoulder. It bruised him badly but didn't break the skin. He stayed on his horse and continued the reconnaissance — that image of the cool, unhurried Protestant hero was born right there. But his men were shaken. The Duke of Schomberg, his second-in-command, urged caution, but William decided to attack the next morning. Lucas: The plan was to feint at the village of Oldbridge, where the main ford was, while sending a large force upstream to cross at Slane and outflank the Jacobite army. William led the main crossing himself, wading into the river under fire. The Dutch Blue Guards took heavy casualties before they could establish a bridgehead. Luna: So this was a direct assault across a defended river — that sounds costly. Lucas: It was. The Jacobite infantry held the bank, and for a while the battle was a close-range firefight across the water. But the flanking column under Schomberg's son, Meinhardt, started crossing at Slane. James had posted only a small force there, and they were pushed back. James himself panicked — he'd been watching from a hill behind the lines, and when he saw his left flank collapsing, he fled for Dublin, effectively abandoning his army. Luna: He just left? Lucas: He did. That's one of the controversies — James had a history of indecisiveness, and his flight meant the battle, which was still fairly balanced, turned into a rout. His Irish troops fought on for a while, but without leadership they fell back in good order. The casualties were actually fairly light — maybe 1,500 Jacobite dead and 500 Williamite. Not a bloodbath by 17th century standards. Lucas: But the strategic consequences were enormous. James abandoned Ireland and returned to France, leaving his Irish supporters to negotiate surrender. William marched unopposed on Dublin, and the war dragged on for another year — culminating in the sieges of Limerick and the Treaty of Limerick in 1691, which we covered in episode 114. Luna: Yet the Boyne became THE symbol, even though the war wasn't over. Lucas: Exactly. The Orange Order, founded in 1795, adopted William's victory as its founding myth. The battle itself wasn't a crushing military defeat — the Jacobite army retreated intact — but it was a decisive political defeat. James lost Ireland, and the Protestant Ascendancy was secured for another century. For Irish Catholics, the Boyne became shorthand for the beginning of the Penal Laws and dispossession. Luna: And for Ulster Protestants, it's still a day of celebration — or at least, of identity. Lucas: Right. The Twelfth of July parades are one of the most visible expressions of unionist culture in Northern Ireland. The Battle of the Boyne is remembered as a victory for religious and political liberty — but that's a selective memory. It was a battle between two kings, both of whom believed in divine right; William was just more pragmatic about working with Parliament. And the 'liberty' won was for Protestants only. Luna: So the battle itself is almost less important than what it came to represent. Lucas: I think that's true. The fighting lasted maybe six hours, and the river crossing was the key tactical moment. But the mythologising — King Billy on his white horse, crossing the Boyne — that's what's shaped Irish history. And it's worth remembering that the Williamite War wasn't just an Irish affair: it was part of the broader Nine Years' War in Europe, pitting the Grand Alliance against Louis XIV. Ireland was a side theatre, but it became a lasting fault line. Luna: Let's talk about the actual crossing — what happened at Oldbridge? Lucas: Oldbridge is a small village on the south bank of the Boyne. The main ford there was narrow, maybe twenty feet across, and the Williamite army had to funnel through it under cannon and musket fire. The Dutch Blue Guards, elite infantry, led the way. They waded into the river chest-deep, holding their muskets above their heads, and took heavy losses from the Jacobite infantry and cavalry who charged into the water to meet them. Lucas: The Duke of Schomberg, who was 75 years old, tried to rally his men and was killed by a sabre cut to the head. His death was a blow, but the sheer weight of numbers eventually pushed the Jacobites back. Meanwhile, the flanking force crossed at Slane and threatened the Jacobite rear, which is what caused James to flee. Luna: That flanking move seems to have been the decisive part. Lucas: It was. James had posted only a small force to guard the fords at Slane, expecting the main attack at Oldbridge. When he saw William's cavalry crossing upstream, he assumed he was being surrounded and ordered a retreat. But the Irish infantry under Patrick Sarsfield fought a rearguard action that saved the army from destruction. Sarsfield became a hero and later negotiated the Treaty of Limerick. Luna: Sarsfield — he's one of the great Irish military figures. Lucas: He is. And his role at the Boyne is often overlooked because of the focus on James's cowardice and William's victory. The Jacobite army actually withdrew in good order, and the war continued for another year. The Boyne was a tactical victory for William but not the decisive blow he wanted. That came later, with the sieges of Limerick and the surrender of the Jacobite forces. Lucas: The treaty that ended the war, the Treaty of Limerick, was remarkably generous — it allowed Catholics to keep their property and practice their religion, and it offered amnesty. But the Protestant Irish Parliament later repudiated most of those terms, leading to the Penal Laws. So the Battle of the Boyne, in the long run, became a symbol of oppression as much as liberation. Luna: It's fascinating how one battle can mean different things to different people. Lucas: That's the power of historical memory. For unionists, it's a triumph of liberty over tyranny. For nationalists, it's the start of the Protestant Ascendancy. But the reality is more nuanced: it was a dynastic struggle that happened to have sectarian overtones. The men who fought on both sides weren't all motivated by religion — some fought for land, some for loyalty, some because they were conscripted. Lucas: If today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. Luna: Yeah, it's a small way to keep the conversations going. Lucas: Alright, back to the Boyne. We haven't talked much about the French involvement. James brought about 6,000 French troops under the Comte de Lauzun. They were regulars, well-trained, and they fought well at the Boyne. But the French and Irish didn't get along — there was cultural friction and suspicion. Lauzun actually advised James to abandon Dublin and fight a guerrilla war, but James refused. Luna: Guerrilla war might have been smarter, given the terrain. Lucas: Possibly. But James wanted a decisive battle. He thought that if he could defeat William in Ireland, it might trigger a Jacobite rising in Scotland or even England. That gamble failed, and he spent the rest of his life in exile at the French court, plotting but never again risking a battle. Luna: What happened to the Irish soldiers who fought for James? Lucas: After the Treaty of Limerick, about 14,000 Irish soldiers went into exile in France and Spain — the so-called Wild Geese. They formed the Irish Brigade in the French army and fought for France for generations. They carried the memory of the Boyne with them. Some of their descendants are still in France today. Luna: The Wild Geese — that's a story in itself. Lucas: It is, and we'll get to it in a future episode. For now, the Boyne stands as a turning point. It didn't end the war, but it ended James's hope of reclaiming his throne. It cemented William's control of Ireland, and it set the stage for the Protestant Ascendancy that would dominate Irish politics for the next 200 years. Lucas: One more thing: the Boyne is also the site of one of the earliest recorded uses of the 'white horse' symbolism. William rode a white horse during the battle — not because it was a special breed, but because it was a common horse for commanders to ride for visibility. That image, filtered through 19th-century romanticism, became the iconic King Billy on his white charger. Luna: So the murals are based on a practical choice, not a mythical one. Lucas: Exactly. And that's the thing about history: the small details often get lost in the big stories. The Boyne is a perfect example of how a six-hour skirmish became a 300-year-old symbol.
