Not really. Here are his exact words from Extract from Augustine's Retractions (Book II, Chapter 66) written by St. Augustine of Hippo in A.D. 426 or 427 and quoted at length in the New Advent Encyclopedia.
"But since there are some persons who so defend God's grace as to deny man's free will, or who suppose that free will is denied when grace is defended, I have determined to write somewhat on this point to your Love, my brother Valentinus, and the rest of you, who are serving God together under the impulse of a mutual love...Now He has revealed to us, through His Holy Scriptures, that there is in a man a free choice of will... [after several Bible quotations] Observe how very plainly is set before our view the free choice of the human will...What is the import of the fact that in so many passages God requires all His commandments to be kept and fulfilled? How does He make this requisition, if there is no free will?...
It is, however, to be feared lest all these and similar testimonies of Holy Scripture (and undoubtedly there are a great many of them), in the maintenance of free will, be understood in such a way as to leave no room for God's assistance and grace in leading a godly life and a good conversation, to which the eternal reward is due... Therefore, my dearly beloved, as we have now proved by our former testimonies from Holy Scripture that there is in man a free determination of will for living rightly and acting rightly; so now let us see what are the divine testimonies concerning the grace of God, without which we are not able to do any good thing... When God says, Turn ye unto me, and I will turn unto you,Zechariah 1:3 one of these clauses — that which invites our return to God — evidently belongs to our will; while the other, which promises His return to us, belongs to His grace. Here, possibly, the Pelagians think they have a justification for their opinion which they so prominently advance, that God's grace is given according to our merits..."
According to this quotation, the false doctrine of Pelagius was that grace is given according to our merits. Then we find this chapter heading in which Augustine says:
Chapter 31 [XV.]— Free Will Has Its Function in the Heart's Conversion; But Grace Too Has Its.
Lest, however, it should be thought that men themselves in this matter do nothing by free will, it is said in the Psalm, Harden not your hearts; and in Ezekiel himself, Cast away from you all your transgressions, which you have impiously committed against me; and make you a new heart and a new spirit; and keep all my commandments. For why will you die, O house of Israel, says the Lord? For I have no pleasure in the death of him that dies, says the Lord God: and turn ye, and live. Ezekiel 18:31-32... There is, however, always within us a free will — but it is not always good; for it is either free from righteousness when it serves sin — and then it is evil — or else it is free from sin when it serves righteousness — and then it is good. But the grace of God is always good; and by it it comes to pass that a man is of a good will, though he was before of an evil one. By it also it comes to pass that the very good will, which has now begun to be, is enlarged, and made so great that it is able to fulfil the divine commandments which it shall wish, when it shall once firmly and perfectly wish.
