At long last, war has come to “Vikings” — and the death of Ragnar Lothbrok (Travis Fimmel) will finally be avenged. The Great Heathen Army has arrived, sights set on Wessex, and King Ecbert (Linus Roache) should be scared.

As the Jan. 25, penultimate episode of Season 4 closed, it was Aethelwulf (Moe Dunford) who ordered his men to charge against the Great Army — with the sons of Ragnar front and center — and we don’t like his chances. The Vikings are hungry for blood, and their numbers might just be too big for Wessex to gain any sort of victory.

So who will survive the battle? Will anyone? Given the amount of royalty in Wessex, chances are not all of them are going to make it out alive. However, thanks to actual historical records, there are some conclusions we can draw.

Ecbert’s grandchildren, for instance, should survive this war. One of the boys, Alfred, goes on to become a major figure in history — and has his own dealings with the Vikings after he’s come to be known as Alfred the Great. Likewise, Aethelwulf historically succeeds his father as King of Wessex, so his death in the battle would be a major shift from actual events.

As for the Lothbrok family, the sons of Ragnar by and large go on to become major figures in their culture — in the cases of Ivar (Alex Hogh) and Bjorn (Alexander Ludwig), even more famous than their father. Given the army they’ve built and the tactics they’re using, it would be surprising to see any of them die.

The beauty of “Vikings,” though, is you never know exactly what’s happening. At any given moment, the tables could turn, and you could be saying goodbye to a beloved character.

So who will survive the battle at Wessex? That’s a question we’re going to have to wait until the finale to learn. Whatever the cast, this is shaping up to be the biggest and most powerful battle in the history of the series.

“Vikings” airs Wednesdays at 9 p.m. ET/PT on History.
