Even while negotiating with Parliamentary moderates, he and Henrietta Maria openly told foreign ambassadors any concessions were temporary, and would be retrieved by force if needed. These suspicions were enhanced after October 1641, when Irish Catholic rebels claimed his approval for their actions, an assertion given weight by previous attempts to use Irish troops against his Scottish opponents, and initial refusal to condemn the rebellion.
