The subject of the sentence is Napoleon's army. It is singular. Except E, all other options incorrectly use 'they' or 'their' to refer the singular subject. Hence, by the process of elimination, the answer is E.

Army is singular and hence needs a singular conjugation.

(A) they had in their previous campaigns (they is plural - incorrect)
(B) their previous campaigns had had (their is plural. Had had is incorrect here. A single "had" would serve the purpose.)
(C) they had for any previous campaign (they is plural - incorrect)
(D) in their previous campaigns (their is plural. The correct possessive reference is "Its" )
(E) for any previous campaign (Correct..."for any" substitutes for "than any of its")

E is correct.
