Background and detail
Strategic Context. During the Franco-Spanish War, a French army under Turenne, supported by 6,000 Commonwealth troops, besieged Dunkirk. An English fleet blockaded the port, preventing reinforcement. The Spanish, including Royalist exiles, mobilized a relief force to lift the siege, unaware that Turenne intended to engage them directly rather than attack Cambrai.
Aftermath and Transfer. The Spanish suffered heavy casualties, with thousands killed, wounded, or captured. Dunkirk surrendered ten days later. Cardinal Mazarin honored the treaty with Cromwell, handing the port to the Commonwealth. This ended the immediate prospect of a Royalist invasion of England. English troops remained to garrison the city under Sir William Lockhart.
