Here's an Augustine quote making a brief reference in passing to definite atonement...
Augustine (354-430): On the other hand, many who glory in the cross of Christ and do not withdraw from that same way, though ignorant of those points which are so subtlely debated, because not one little one perishes for whom He died, attain to that same eternity, truth, charity, that is, to a fixed, sure, and complete happiness where all things are clear to those who remain faithful, who see, and who love. FC, Vol. 30, Saint Augustine Letters, 169.4 Addressed to Evodius (end of 415 AD) (New York: Fathers of the Church, Inc., 1955), p. 54.
Latin text: et multi in cruce Christi gloriantes, et ab eadem via non recedentes, etiamsi ista quae subtilissime disseruntur, ignorant, quia non perit unus ex illis pro quibus mortuus est, ad eamdem perveniant aeternitatem, veritatem, charitatem, id est ad stabilem, certam, plenamque felicitatem, ubi manentibus, videntibus, amantibus sunt cuncta perspicua. Epistola CLXIX, Cap. 1, §4, PL 33:744.
