Ritz, Judge:
In 1886 the plaintiff purchased from one Jasper M. Porter certain real estate in the county of Hancock, and for the *247deferred instalments of purchase money executed certain non-negotiable notes. These notes were held by Porter until about the year 1893, when they were transferred to the defendant James M. Porter, who held them until the year 1907, when he transferred the same to Ms sister Fannie Porter McBride, who has since died, and who is represented in this suit by the defendant W. D. Porter as the executor of her will. After the death of Fannie Porter McBride, her executor threatened to execute a deed of trust given to secure these notes, and the plaintiff then brought this suit for the purpose of cancelling the notes and can-celling the deed of trust as a cloud upon Ms title to the real estate. The theory upon wMeh he proceeds is that in the year 1893 and prior thereto the defendant James M. Porter became indebted to him in considerable sums of money, and that he importuned the said James M. Porter to make settlement with him of this indebtedness in order that he might meet his obligation to Jasper M. Porter on account of these notes; that James M. Porter in the year 1893 told Mm that he would acquire; the notes Mmself from Jasper M. Porter, and would settle the indebtedness to the plaintiff insofar as the notes would cover the same in that way. As before stated, James M. Porter did acquire the notes at that time and ,so advised the plaintiff, and the plaintiff believed, as he alleges, that the arrangement for settling the same with the indebtedness of James M. Porter to him was entirely satisfactory. After James M. Porter became the owner of the notes the plaintiff at various times, as he testifies, attempted to have Porter cancel the same and deliver them to Mm, but Porter always delayed doing tMs, not upon the ground that the plaintiff was not entitled to have it done, but upon the ground’ of inconvenience and like excuses. Plaintiff’s contention was that the indebtedness of James M. Porter to Mm not only fully satisfied the notes at the time they came into Porter’s hands, but was in excess of the amount of the notes, and he desired to have the notes cancelled and the deed of trust removed as a cloud upon Ms title, and a decree for any balance said James M. Porter might owe him.
The case was heard by the circuit court, and the plaintiff’s *248bill dismissed, but upon appeal to this court that decree was reversed, and this court held that the plaintiff was entitled to have the indebtedness of Porter to him set off against these notes; in other words, it was held that the plaintiff’s contention as to the arrangement between him and James M. Porter was proved, and that he was entitled to relief thereon, and remanded the cause with the suggestion that it was one where a reference to a commissioner would likely be proper to ascertain the correct amount of the various items in the plaintiff’s account, and to- apply the same to the notes .in question. See Marshall v. Porter, 71 W. Va. 330. After the cause was remanded to the circuit court it was referred to a commissioner, and the commissioner made a report finding that Marshall was entitled to have the notes cancelled as fully satisfied, to have the deed of trust also cancelled, and to have a recovery against James M. Porter for a small amount in addition thereto. The circuit court decreed accordingly, and this appeal is prosecuted.
Some question is made as to the sufficiency of the proof to establish certain debts claimed by Marshall, or rather to establish the amount of them as they were found by the commissioner. Upon this question it suffices to say that there is evidence in the case fully supporting the commissioner’s' findings as to the amount of these particular debts, even though it may be in some instances controverted, and this court will not reverse the decree of the circuit court approving the findings of a commissioner upon controverted facts, unless such finding is clearly against the weight of the evidence. Such is not the ease here. One of these items was for the interest of the. plaintiff in an oil well, the legal title to which was in the defendant' James 'M. Porter. It is shown that James M. Porter sold this well and took the money himself, and never accounted to the plaintiff for one cent, although it is admitted that the plaintiff had a considerable ..interest, therein. The defendant James M. Porter has always refused, and even when he testified in this case refuse^. to say how much he got for this well, or to' whom he sold it. • The commissioner could do nothing but take the best evidence he could get as to this, and we think his findings are as advantageous to the defendant James M. Porter *249as be could reasonably expect, particularly in view of the fact that it lay in his power to make the matter absolutely certain.
In the circuit court, when the report of the commissioner came up for consideration, the defendant James M. Porter for the first time by exceptions set up the Statute of Limitations as a bar to any of the claims asserted by the plaintiff. Insofar as these claims were applied to the discharge of the notes set up and referred to in the bill there is nothing in this contention. The agreement, which this court by its former decree found existed between the parties, was to apply this indebtedness of James M. Porter to Marshall to the extinguishment of these notes. Having found that that agreement existed, a court of equity looks upon that as done which ought to be done. We will treat the notes executed by the plaintiff, and which are sought to be cancelled here, as satisfied and discharged as of the time James M. Porter and the plaintiff agreed that it should be done. Story’s Equity Jurisprudence, § 81; Felch v. Hooper, 119 Mass. 52; Craig v. Leslie, 3 Wheat. 563. But does the Statute of Limitations apply to the decree in favor of the plaintiff for the excess of his indebtedness above the notes held at the time by the defendant James M. Porter? As before stated, these claims were set up by the plaintiff in his bill filed in this case, and while they were not particularized in that bill, they were gone into by particular items in testimony taken in support of it. The defendant James M. Porter at that time denied their validity, and denied that the plaintiff had the right to discharge the notes referred to in this case in that way, or to recover any of said claims. The parties, after full opportunity to offer all of the matters they had in support of their respective contentions, submitted the case for a decision,'and this court on appeal held that the plaintiff was entitled to recover, his claims in this suit. That decree established the validity of them, and the only thing left for determination was the amount thereof and their application to the notes in controversy. The defendant James M. Porter could not reserve one of his defenses. He had full opportunity to make all defenses at that time, and not having made his defense of the Statute of Limitations then the finding of this court *250establishing the validity of the plaintiff’s claims is res ajudi-cata, and we will not now re-open that question and allow him to plead the Statute of Limitations to prevent a recovery against him for the amount in excess of the notes which were cancelled by the court’s decree. It is fundamental that -where a party is sued, and he challenges the validity of the cause of action against him, he must put in all of the defenses he has thereto. If he fail to do so he will not be allowed after a decree or judgment against him upon the merits to assert a defense which was available to him before the rendition of such adverse judgment or decree.

It follows from what we have said that the decree of the circuit court of Hancock county complained of will be affirmed.
Affirmed.
