Here are some corrections :

Durant l'été 1944, le Général William Donovan, directeur du Bureau des Services Stratégiques, a décidé /décida  de rédiger un historique/une histoire (générale) de l'agence

[Katerina James]

Passe compose expresses a past event or action that the speaker sees either as completed in the past or as related to or  having consequences for the present.

 

Passe simple was used to label a past action as completed in the past with no reference to the present.

 

Perfect!!
