In Irish terms the Battle of the Yellow Ford was a big one perhaps 9,000 men fought in it. It is also often misunderstood. Surviving Irish sources don't say overmuch about it and the English ones contradict each other. Everyone agrees on the outcome the largest English Army ever sent to Ireland was destroyed. At the end of it half of the English Army was dead or wounded. The General and 18 senior officers were dead. Three hundred or so troops deserted to the Irish. The survivors surrendered their arms and equipment in exchange for their lives.
There is something of the Hollywood epic about the battle. The two opposing Generals were related and loathed each other. Field works played an important part in deciding the outcome and, unusually for Ireland, cannon were used on the battle field. How it happened has long intrigued me and I have written a series of posts on what I have learned. If it's of interest the first one is now on my blog.
