It is often said that Cromwell visited ‘genocide’ on the Irish, but where is the evidence for this? The most cited example, the butchery at Drogheda, occurred as the result of the Irish Royalist’s refusal to surrender, necessitating the Parliamentarian Army storming the town, taking heavy casualties as a result, and according to the rules of war at the time, the garrison thus had no right to expect quarter. In any case, far from all the people in Drogheda were killed.
I'm not talking about Drogheda which was war and you are correct that this was as per the rules of war
I'm talking about the Sack of Wexford, and John Hewson destroying food stocks in counties Wicklow and Kildare and other places and the English's scorched earth policy whereby folks would be slain and their cattle and goods taken or spoiled. This led to famine.
At the same time the Irish were sold as indentured labor throughout the colonies
