- Lucas: So we've talked about the Treaty of Limerick and the Wild Geese, and about how the Penal Laws locked in Protestant dominance for generations. But the hinge — the single military event that made all that possible — was the Battle of the Boyne in 1690. Luna: The Boyne — that's July 12th, right? The big Orange march. Lucas: Exactly. Though the actual battle was fought on July 1st old style, July 11th new style — the confusion around calendars is a whole other story. But yes, the Twelfth of July commemorates King William's victory over King James. And the battle itself is one of the most mythologised in Irish history — but the real story is even more interesting. Luna: Okay, let's set the scene. Two kings, one river — that's the image, right? Lucas: Right. By June 1690, James II had been deposed in England and replaced by his Protestant daughter Mary and her husband William of Orange. James fled to France, and with Louis XIV's support, he landed in Ireland in March 1689 to raise an army from his Catholic supporters. For over a year, the Jacobites controlled most of Ireland except for Protestant strongholds like Derry and Enniskillen. William landed at Carrickfergus on June 14, 1690, with a multinational army — English, Dutch, Danish, German, and French Huguenot troops. Luna: So it was a European war playing out on Irish soil. Lucas: Absolutely. The Jacobite army was mostly Irish Catholics, but they were commanded by French generals sent by Louis XIV — Lauzun was the overall commander, and the Irish officers were often sidelined. James himself was there, but he was no military genius. Meanwhile, William's army had veterans from across Europe, and he was a proven commander. Lucas: The armies faced each other across the River Boyne near Drogheda on June 30. William scouted the river himself and was nearly killed by a Jacobite cannonball that grazed his shoulder. That story became legend — a sign of divine protection. Luna: Wait — he was actually hit? Lucas: He was. The ball tore his coat and drew blood, but he stayed on his horse and continued the reconnaissance. It made a huge impression on his troops. The next day, July 1, he put his plan into action. Lucas: William sent a large part of his army upstream to cross at Slane and Rosnaree, threatening the Jacobite left flank. James and Lauzun took the bait and moved most of their forces north to block them. But that was the diversion. The main crossing would be at Oldbridge, a ford about four miles downstream, where William's elite troops — Dutch Blue Guards, Danish infantry, and Huguenot regiments — waded into the river under heavy fire. Luna: So the crossing was the real fight. Lucas: It was brutal. The Jacobite infantry, many of them raw recruits, held the south bank and poured musket fire into the Williamites as they struggled through the water. The Dutch Guards took heavy casualties — their commander, the Count of Solms, had to be restrained from charging too early. But once they got a foothold on the south bank, the Jacobite line began to waver. Lucas: The Duke of Schomberg, William's 75-year-old second-in-command, tried to rally some Huguenot troops who were faltering and was cut down by Jacobite cavalry. That was a serious blow. But William himself crossed later in the day, and his presence steadied the line. Luna: Schomberg was that old and still in the field? Lucas: He was a veteran of decades of European wars. His death was a real loss. But the battle was already turning. The Jacobite cavalry, led by men like Patrick Sarsfield — who we talked about in the Siege of Limerick episode — fought bravely, covering the retreat of the infantry. But by mid-afternoon, the Jacobite army was in full retreat toward Drogheda. Lucas: James II fled to Dublin, then to Waterford, and finally back to France. He famously told Lady Tyrconnel that the Irish had run away, which was actually unfair — the Irish infantry had held their ground at Oldbridge for hours against superior numbers. But James's own nerve had failed. Luna: So the battle itself wasn't as decisive as people think? Lucas: It was indecisive in a tactical sense — the Jacobite army was still intact and would fight on for another year, culminating at Limerick. But strategically, it was decisive. William's victory meant he controlled Dublin and the eastern half of Ireland. It also cemented Protestant morale and the idea that God favoured the Protestant cause. The Boyne became the symbolic foundation of the Protestant Ascendancy. Lucas: And the commemorations started almost immediately. By the 1690s, Irish Protestants were marching on July 1st to celebrate. When the calendar changed in 1752, the date moved to July 12th, and the Orange Order was founded in 1795 to defend that legacy. To this day, the Twelfth is the biggest day in the Orange calendar. Luna: But the real battle happened at different fords, not just one glorious charge. Lucas: Exactly. The myth has William crossing the Boyne on a white horse in a single heroic moment. In reality, it was a messy, hours-long fight across multiple crossing points, with heavy casualties on both sides — maybe 1,500 Williamites and 1,000 Jacobites killed. Not a huge battle by European standards, but hugely symbolic. Lucas: Speaking of symbolism — the Boyne is also one of those battles that gets oversimplified as 'Catholic vs Protestant'. But William's army included Catholics — the Pope actually supported William because he was fighting Louis XIV, a rival Catholic power. And James's army had English and French Protestants fighting alongside the Irish. Religion was important, but so were geopolitics and dynastic loyalty. Luna: That's a good reminder. So what happened to the Jacobite army after the Boyne? Lucas: They fell back to Limerick, where Sarsfield organised a brilliant defence that held out until October 1691. That siege we covered in Episode 127. But the Boyne broke James's resolve. He left Ireland for good, telling his supporters they should look after themselves. The war continued, but the psychological blow was immense. Lucas: There's a moving account from a Williamite chaplain, George Story, who wrote about the battlefield the next day. He described the bodies floating in the river, the cries of the wounded, and the silence that fell after the fighting. It's a reminder that for all the marching bands and banners, this was a bloody, brutal day. Luna: And it's still being fought over in a way, isn't it? The memory of the battle. Lucas: Absolutely. The Boyne is still a live political symbol in Northern Ireland. Every July, the marches can stir up tension. But understanding what actually happened — the tactics, the personalities, the complexities — can maybe take some of the heat out of it. It was a battle in a European war, not a simple religious showdown. Lucas: I think that's the value of digging into these events. The more we know, the less we can reduce them to slogans. Luna: Well said. Thanks for walking us through it. Lucas: Always a pleasure.

It keeps us ad-free and lets us spend the time to get the details right — like tracking down George Story's account or verifying the crossing points at the Boyne. Every little bit helps. Luna: Yeah, and we really do read the original sources so you don't have to. Lucas: Exactly. So next time, we'll look at what happened in the months after the Boyne — the final Jacobite stand at Limerick and the treaty that sent the Wild Geese into exile. Until then, keep questioning the stories.
