In the thread on military historical dates Karl claims that the Battle of Culloden in 1746 was ''debateable'' as a battle between England and Scotland.
The facts are that the Jacobite rebellion was based on the Stuart (Scottish ) line of succession to the combined English and Scottish thrones. That direct line of succession ended on the death of Queen Anne, who had no issue, and her successor was the German George I.
The Jacobites intended to reinstate the Scottish line of succession, by raising rebellion in Scotland. Having done that the Scottish clans invaded England in the expectation of raising support there.They failed to raise any support, and having got as far south as Derby had to retreat all the way back into Scotland.
The Battle of Culloden thus was the outcome of a Scottish invasion of England, the battle resulting in the re-imposition of the rule in Scotland by the house of Saxa-Coburg-Gotha in place of the Stuarts.
I don't think that the fact that the winning side included Scots detracts from the fact that it was an England versus Scotland conflict.
