After a year of intense study, I'm still so confused about indirect and direct object pronouns. Especially when sentence like this "El capitan les manda que los soldados descansen. Les manda descansar". I understand that in order to have an indirect object in a sentence, there must be a direct object, either real or implied. It's was quite easy with verb like dar, traer, vender, prestar, etc. because it implied give something, bring something, sell something, that something an direct object. But with verbs like "mandar", what is the "direct object"?
