Mr. Justice Matthews

delivered the opinion of the court.

In a maritime cause of collision arising on the waters of the Mississippi River, the owners of the steamboat Sabine filed their libel in the District Court of the United States for the Eastern District of Louisiana, against the steamboat Richmond, to recover damages for the loss alleged to have been occasioned by the fault of the latter. The owners and claimants of the Richmond, being the plaintiffs in error in this *199 cause, defended against the libel filed by the owners of the Sabine, and also filed'- a cross libel,' alleging damage to the Bichmond in the collision caused by the fault of the Sabine, and claiming -damages., therefor. A decree was rendered in "this cause "¿Túne 5, 1873, against the steamboat Sabine and her owners, Sarah C. Shirley, B. F. Fuller, and-America B. Selby, and Nathaniel C. Selby, her husband, together with Alfred Moulton, Charles Cavaroq, Jules~Tuyes,. and Achjlle Ohiapella, the. four last named being sureties for the owners of the Sabine -in a bond for. the sum. of -$8000, conditioned to pay any damages adjudged in favor of. the owners of the Bichmond as cross, libellants in the suit, which the libellants had been required by the court to give. The amount of the decree against the owners of the Sabine, as principals, was $9750 damages,' -besides costs, and against each of the four named sureties the sum of $2000, that being the amount limited in the obligation as the several liability of each. From this decree all the parties appealed to the Circuit' Court of f the United States for the Eastern District of Louisiana.; For. the purpose of perfecting the appeal, Fuller, Moulton, Cavaroc, Tuyes, and Chiapella executed arid filed an appeal • bond in the sum of $20,000, the condition of which was that if they should prosecute their appeal to effect, and answer all damages and costs, and satisfy whatever judgment might be rendered against them if they failed .to make their appeal good, the obligation should be void; and on this bond J. W.TIincks and. Pierre S. Wiltz, two-of the defendants in error,-were sureties, each in the sum of $5000. The- causé was heard bn this appeal in the Circuit Court on the 11th of March, 1876, when . a decree was rendered in the cause, dismissing the original libel, maintaining the cross libel, and condemning the original libellants, the owners of the steamboat - Sabine, together with their sureties in the original' bond- of- $8000, viz., Moulton, Cavaroc, Tuyes, and Chiapella, to pay to the owners of the steamboat Bichmond a,s damages the sum of $7392.60, with costs. The decree of the Circuit Court as against Moulton,-Cavaroc, Tuyes, and Chiapella, sureties as aforesaid, was several as against each in the sum of $2000, that being the *200 amount for 'which they respectively bound themselves. From this decree of the Circuit Court the owners' of the steamboat Sabine, the original libellants, together with the Merchants’ Mutual Insurance Company, the. Mechanics’ and Traders’ Insurance Company, the Factors’ and Traders’ Insurance Company, the New Orleans Mutual Insurance Company, the Sun Mutual Insurance Company, Ihe New Orleans Insurance Association, the Crespent Mutual Insurance Company, and the Commercial Insurance Company, all which insurance companies were libellants and intervenors in certain other similar causes consolidated with that of the original libel of the owners of the Sabine against the Richmond, joined in an appeal to the Supreme Court of the United States from the several decrees rendered in the consolidated causes, including that in which the present defendants in error were parties. The bond given for the prosecution of that appeal to the Supreme Court was in the sum of five hundred dollars, and did not operate as a supersedeas. The defendants in error in this cause were not parties to this appeal. The appeal from the decree of the Circuit Court wTas heard at the October term, 1880, of the Supreme Court, when it was ordered and decreed that the decree of the Circuit Court appealed from should be and the same was affirmed. Subsequently an execution was issued on the decree of the Circuit Court, running against Moulton, Cavaroc, Tuyes, and Chiapellá, for the sum of $7292.60, with interest at'five per cent, per annum from March 11, 1876, and costs. Motions'were made on May 3, 1881, on behalf of Moulton and Tuyes, defendants in that' execution, to quash the samé on the ground that the said decree, as against each of the said suretiés,' had been satisfied and discharged. These motions came on to be heard June 16, 1881, on consideration whereof they were allowed, and the writ of fieri facias quashed, and the marshal ordered to desist from any further proceedings thereunder.

The plaintiffs in error thereafter, on the 7th of March, 1882, being’ the owners of the steamboat Richmond or their representatives, commenced this action against the defendants in error, as parties to the appeal bond given for the prosecution *201 of the appeal from the original decree of' the District Court to the Circuit Court. The- defendants rely upon two defences: 1st, That the matters in controversy were- finally adjudged in their favor by the Circuit Court on the motion to quash • the execution issued-against them on its decree, so as to constitute an estoppel upon the principle of res judicata ; 2d, That'the decrees of the Circuit Court against them respectively were discharged'by payments made and accepted in full satisfaction thereof, by way of compromise, prior to the appeal taken by the other parties to the Supreme Court.of the United' States. The. cause came on to be heard before the Circuit Court on .May 29, 1883, when the parties, having duly waived the intervention of a jury, submitted the cause to the court; on .consideration whereof, the court rendered judgment in favor of the defendants. The object of the present writ of error iUlo reverse that judgment.

It appears from the bill of exceptions taken on the trial that the plaintiffs below, to maintain the issues on their part/'put in as evidence in said cause the appeal bond, decree and final judgment, and the mandate of the Supreme Court of the United States, as the same are described and-referred to in the plaintiffs’ petition, and also the amount of costs taxed' in the cause, amounting, to the sum of $15.93.45, and rested their case. Thereupon the defendants, to maintain the issues on their part/' put in evidence, among other matters, the following:

1st. The decree rendered by the District Court against the owners of the Sabine in favor of the cross, libellants, the owners of the Richmond, showing the amount decreed against the sureties on the bond of $8000 to be .the sum of $2000 each.

2d. The decree of the Circuit Court in the same cause in the amount of $1392.60 in sólido against the owners of the steamer Sabine, and against the sureties on the original bond for $8000 in the sum of $2000 each.

3d. The petition and allowance of the appeal from that decree to the Supreme Court of the United States, together with the appeal bond for the prosecution thereof.

4th. The record of the proceedings in the Circuit Court on the motion to quash the execution, together with the judg *202 ment of the court allowing said motion and quashing the said execution.

5th. Four written papers signed by Kennard, Howe & Prentiss, attorneys of record for the owjiers of the steamer Richmond in the proceedings in admiralty, showing payments made by the parties respectively in satisfaction of the decree of the Circuit Court against them, which papers are as follows:

It was then proved by John- Kennard, a member of the firm of Kennard, Howe & Prentiss, that he signed the papers b}r the firm name of Kennard, Howe & Prentiss, who were the attorneys for the steamer Richmond; that he received the sums of money in the said papers severally mentioned, and that he executed the said papers under plenary authority from. the' plaintiffs to make the compromise. The plaintiffs then offered to prove by the same witness that the proctors for the owners of the steamer Sabine opened a negotiation with him to compromise said case, and offered to pay the sum of $5000 for a compromise of the litigation then pending between the parties, and threatened an appeal from the decree and judgment of the Circuit Court, which had been rendered in favor of the owners of the steamer Richmond, unless said money should be accepted and said compromise effected; and that for the pur *204 pose of ending said litigation lie accepted said money and compromised said case; that it was expressly agreed by the parties to that cause that said litigation was then ended, and that no appeal should be taken from the said decree and judgment of the Circuit Court. To this offer and evidence the defendants objected on the ground that the papers in evidence constituted a contract in writing between the parties, and that no parol evidence impeaching them could be received. The court sustained the objection, and refused to hear the evidence, to which ruling the plaintiffs excepted.

It is not important to determine what effect^ if any, should be given to the proceedings and order of the Circuit Court on-the motion of the defendants Tuyes and Moulton to quash the execution issued on the decree against them. It does not appear from the record of these proceedings on what .ground the judgment of the court was placed, and 4n its terms it is not final, as it merely quashes the particular writ of execution then in the marshal’s hands, and directs him to take no further proceedings thereunder. If it had been based upon a finding of a payment of the decree, or of an accord -and satisfaction-equivalent to payment, and had directed satisfaction' of the decree to be entered of record, as it clearly had power to do in such a proceeding, the judgment would have been conclusive as a defence to the bond in suit, notwithstanding the summary character of the proceeding. United States v. McLemore, 4 How. 286; Perkins v. Fourniquet, 14 How. 328. But the introduction of the record of these proceedings as evidence did not prejudice the plaintiffs in error, for the other evidence in the cause; and which no doubt is the same on which the Circuit Court acted in that proceeding, shows an accord and satisfaction equivalent to a payment of the decree, and, in equity, to a satisfaction and discharge. It is so expressed in each of the papers executed at the time, which, although they are in one sense receipts acknowledging the payment of money, are also written evidence of an executed agreement by which the money was received in full payment and settlement of the decree and of the bond given for its payment now sued on. It is shown that the attorneys for the *205 owners of the Richmond, who signed those receipts, were fully authorized to do so. The Contract in each case is with the individual defendant for a satisfaction of the decree rendered against him severally. The payment and receipt of the money in pursuance- of the agreement amounted to a release of errors, so that there was a valuable consideration to sustain the contract whereby a less sum than the amount due by the decree was received in full payment.

The offer on the part of the plaintiffs in error to prove by parol , another condition of the' contract, viz., that the other defendants, the owners of the steamboat Sabine, and the intervenors 'and other parties, the several insurance companies who had become parties to the appeal, should not take and perfect an appeal to the Supreme Court of the United States, was rightly rejected, because such parol evidence necessarily varied and contradicted the written agreement of the parties. The papers in evidence established a complete accord and satisfaction -fully performed, in pursuance of an agreement to extinguish the liability of the defendants by reason of the original decree, and .so to satisfy the obligation ,pf the bond on 'which they are sued. The right of the defendants to appeal from the decree, and the fact that they had declared their intention to do so, created such a dispute in respect to their liability as made it a proper subject of compromise. A compromise was made and fully performed on their part; they paid the money, which was received in payment of the decree, and took no appeal. It is not now open to the plaintiffs in error to treat this payment merely as a credit on account and hold the defendants to their original liability. United States v. Child 12 Wall. 232; Oglesby v. Attrill, 105 U. S. 605.

The technicality difficulty, that there can be no satisfaction and discharge of a judgment or decree, except by matter of record, Mitchell v. Hawley, 4 Denio, 414; S. C. 47 Am. Dec. 260, cannot be interposed. At common law actual payment of a debt of record could not be pleaded in bar of an action for the recovery of the debt. This has been changed by statute both in England and in this country, and no reason can be assigned why an accord and satisfaction should not have *206 the same effect. In. the present case the action is not on the decree, but on the appeal bond, and for the recovery of damages arising from the breach, as to/which matters in pais, such as payment or accord and satisfaction, were always a good plea.

Judgment affirmed.
