At that point Mazarin drew upon Plessis-Praslin's army for reinforcements to be sent to subdue the rebellion in the south forcing the royal general to retire. Then Archduke Leopold Wilhelm decided that he had spent enough of the king of Spain's money and men in the French quarrel. His regular army withdrew into winter quarters, and left Turenne to deliver the princes with a motley host of Frondeurs and Lorrainers. Plessis-Praslin by force and bribery secured the surrender of Rethel on 13 December 1650 and Turenne, who had advanced to relieve the place, fell back hurriedly. But he was a terrible opponent, and Plessis-Praslin and Mazarin himself, who accompanied the army, had many misgivings as to the result of a lost battle. The marshal chose nevertheless to force Turenne to a decision, and the Battle of Blanc-Champ (near Somme-Py) or Rethel was the consequence.
