Anybody know about a Micheal McGlynn who was involved with the Ballyseedy event in kerry in 1918?

I am not sure about this, but are we talking about the incident when Free State soldiers retaliated for the killing of 5 of there own by Anti treaty forces by tying 9 prisoners to a land mine and exploding it. Those who survived were then machine gunned. There was one survivor, can't recall his name but it wasn't your man,
