The number of casualties was simply staggering. In just two hours, 14,000 people lost their lives in the bloody Battle of Flodden.
And as TV star Robson Green admits, it is a figure which is simply ‘extraordinary’.
The 48-year-old visits the scene of the conflict in the fourth episode of his Tales from Northumberland series.
His visit coincides with the 500th anniversary year of the battle.
And it is a history lesson which Green will remember for a long time.
“Learning about the forgotten war was great,” he said.
“It is probably the most dramatic battle Great Britain has ever seen, and it happened right here in Northumberland.
“It changed British history.We remember all the great battles, but everyone forgets this one. In two hours, 14,000 men lost their lives in hand-to-hand combat; it is just extraordinary. It is very emotive.”
Green also experiences the Flodden500 ride-out, which commemorated the men who fell in the 1513 conflict.
He said: “The battle is remembered every year with the ride-out. Because it was the 500th anniversary, there were 500 horses charging to remember the dead on both sides.”
Green meets local historian Clive Hallam-Baker during his time at the Flodden battlefield, which has attracted around 40,000 visitors this year.
Clive, who is chairman of The Remembering Flodden Project, said: “Robson looked at the landscape and he was amazed.
“He had no idea that this sort of thing happened; that such a major battle, with such a huge loss of life, should take place in such a quiet part of Northumberland.”
“We also did a bit of filming with some replica weapons and he was amazed at the potential viciousness of the weapons. It brought it home that this battle was nasty hand-to-hand combat.”
Green is very busy in episode four, which is aired on Monday. He also visits Chillingham Castle and fortified farmhouse Black Middens Bastle. Berwick is on the agenda too, including the town’s football club and the Lowry Trail.
