Take the following sentence:
Fast die Hälfte des Gartens war einer Garage geopfert worden.
I can't help thinking that there needs to be a "für" inserted in there between the "war" and the "einer", because without it it seems to me that the translation would be, "Nearly half the garden had been sacrificed a garage". Which doesn't make sense without a "for".
So my question is : should the sentence written in German, above, contain the word, "für"?

No, the sentence is correct. "einer Garage" is dative case, which automatically means "for the garage" in this case. I think English needs "for" to clarify because in English there's no visible/audible distinction between nominative, accusative and dative case.

In colloquial speech "für eine Garage" may be used here, but strictly correct is "einer Garage".
