French military planners had to balance competing demands for the 1781 campaign. After a series of unsuccessful attempts at cooperation in America (leading to unsuccessful attempts on Newport, Rhode Island and Savannah, Georgia), they decided more involvement in North America was necessary.[66] They also needed to coordinate their actions with Spain, as there was potential interest in making an assault on the British stronghold of Jamaica. It turned out that the Spanish were not interested in operations against Jamaica until after they had dealt with an expected British attempt to reinforce besieged Gibraltar, and merely wanted to be informed of the movements of the West Indies fleet.[67]
