John O'Neill approached Philip IV with another proposal for an invasion in 1630; this proposal was rebuffed. During his time in Madrid, O'Neill was made a Knight of Calatrava and a member of the Spanish Supreme Council of War. In 1639, another request by O'Neill to the Spanish king Philip IV that he be allowed lead a Spanish army to Ireland was rejected. In 1641, Rory O'More, unaware of O'Neill's death, sought his assistance for the planned rebellion of 1641.
