The Siege of Kinsale was the most important engagement of the Nine Years' War, the biggest rebellion to take place in Ireland during the Tudor period. IOTL the English defeated the rebels and their Spanish allies, eventually crushing the revolt entirely roughly a year later. But what if the Irish alliance won? IIRC they had a decent shot at doing so IOTL, but they failed to coordinate with the besieged Spaniards effectively, both sides being defeated in detail as a result.
What would happen after such a victory? Could the English be thrown out of Ireland entirely, and if so, what would it look like? For example, who would govern it, a local Irish noble or some foreign prince? I assume Spain would be overjoyed, to put it mildly, by this blow to English prestige - even their OTL victory was extremely expensive, and a loss would be even more so. Would London try to reassert control over it in the future?
