Ok you want to try some specifics there? Can you actually give the times and dates of these occasions on which British soldiers threw grenades into homes, believe me I grew up in Catholic Nationalist Ireland and even I never heard this one, so tell us when did this happen? The throwing of grenades into the homes of civilians by British troops would have achieved quite a bit of attention even in the 1920's so can you post the links so we can check it out? Or is this just a load of baloney that your oul' uncle Mickey used to rant about after he came back from the pub?
As a small point of information Cromwell, a Republican, did not massacre Irish citizens, the massacre for which he is most famous happened in Drogheda where he massacred the garrison which were English Royalists holding out for King Charles.
Ah facts facts don't ya just hate them when your discussing them with Irish Americans?
Probably referring to the Black & Tans who were more of a paramilitary than regular army.
