delivered the opinion of the court.
This was an action on a bond executed by the defendant Hill to the plaintiff — who had been copartners in the carriage business — containing the following condition: “ That whereas the said John H. Hill having purchased the interest of the said James R. Ham, in the firm of Ham & Hill, in the carriage business, in the city of Boonville, Missouri, and has agreed with the said Ham to assume all partnership liabili*278ties of the said firm incurred between the 1st day of April, 1858, and the 1st day of July, 1858, and to pay the same whenever payment is demanded legally by the creditors of said firm : Now if the said Hill shall observe and keep said agreement and pay said debts in manner and form above prescribed, then this bond to be void, otherwise to remain in full force.” The petition alleges, as breaches of said bond, the failure of the defendant to pay certain debts of the firm, which are particularly specified in the petition, accruing within the period mentioned in the bond, payment of which had been legally demanded ; and that suit had been brought against the plaintiff by the creditors of the firm to recover said debts. There was a demurrer to the petition, which being sustained, the cause is brought to this court by writ of error.
The question for our consideration is whether a right of action accrued on the bond upon the failure of the defendant to pay the debts it provides for according to its stipulation; or is it a bond of indemnity merely ? We think it is clearly to be collected from the terms of the instrument in suit that it was not the intention merely to secure the plaintiff against actual loss or damage, or that it created an obligation which was contingent upon the payment by the plaintiff of the debts it provides for. It is a bond with an affirmative covenant to do a certain thing; the defendant thereby bound himself to take the place individually of the firm, and discharge debts for which it was liable, and which, as it respects the parties themselves, became by the bond the individual debts of the defendant. Although the legal liability of the firm to its creditors is not changed by the instrument, yet, as to these firm debts, it creates the relation of creditor and debtor between the plaintiff and defendant, and the assump-sit by the defendant is equivalent to a direct- promise to pay money to the plaintiff. In promising to pay debts for which as a firm they were jointly liable, the defendant thereby incurred an obligation which was violated, and for which a right of action accrued to the plaintiff when he failed to pay them *279on demand of the creditors. If A. for a sufficient consideration enter into a covenant with B. to pay the creditor of B. a given, sum at a specified time or when it should be legally demanded, there could be no doubt of the meaning and legal effect of such an instrument, and that the default of A. to pay at the time agreed upon would give B. an immediate right of action, without waiting until he had made payment of the debt. The case before us and the one supposed are not distinguishable. In the former, the obligor assumes, for the consideration therein expressed, all the partnership debts accruing within a given period, and expressly agrees to pay them whenever payment is legally demanded.
The distinction between bonds of indemnity and covenants to perform a particular act, is well illustrated by the authorities cited by counsel for the plaintiff, and fully sustain our view of the nature and effect of the covenant in this case. In the case of Holme v. Rhodes, 1 Bos. & Pul. 640, the suit was on a bond with a condition that the obligor, who was principal on an obligation to pay money to a third person in which the obligee was surety, should pay the debt by a certain time and thereby acquit the obligee; the defendant pleaded non damnificatus. This plea was held to be no answer to that part of the condition by which the defendant undertook to pay the sum for which "the obligee was bound. In a note to Cutter v. Southern, 1 Saund. 117, Sergeant Williams states the rule to be, that in all cases of conditions to indemnify and save harmless, the proper plea is non damni-ficatus. This plea, however, can not be pleaded, where the condition is to discharge or acquit the plaintiff, for there the defendant must set forth the special manner of performance. But it is otherwise where the condition is to acquit plaintiff from any damage by reason of such bond or other particular thing, for that is in truth the same thing as with a condition to indemnify and save harmless. Loosemore v. Radford, 9 M. & W. 656, is an instance of the application of the principle in a suit by a surety against the principal on his cove*280nant to pay the amount for which they were jointly liable on a given day, in which it was held that the right of action accrued on default of paying at the specified time and for the full amount. Post v. Jackson, 17 John. 238, which was affirmed on error (ib. 480) sustains the view we have taken of, the instrument sued on, both as it respects plaintiff’s right of action upon it before payment of the debts, and also as to the rule of damages he contends for. In that case the plaintiff was a lessee of certain premises and had covenanted to pay the rent; he assigned to the defendant, who covenanted with the plaintiff that he (defendant) would perform the plaintiff’s covenants in the original lease to him. The averment was that rent of a given amount was in arrear and due and unpaid to the original lessee. The covenant was held not to be a mere covenant of indemnity. The Chancellor drew a distinction between an undertaking to acquit and discharge from any damage by reason of the bond and a covenant to do an act in discharge of the plaintiff from such bond or covenant, and remarks that it would be a perversion of the plain sense and language of the covenant in that case to turn it into a mere covenant to indemnify.
In Thomas v. Allen, 1 Hill, 146, the principle of Post v. Jackson is recognized and applied to a case where a bond was given conditioned to pay plaintiff a sum of money by satisfying a bond and mortgage executed between three persons, and to save the plaintiff harmless. The breach assigned was that the sum agreed to be paid was due and payable on a specified day on the bond and mortgage, and that the defendant had not paid or satisfied the same. On a demurrer that this was a bond of indemnity and that the breach did not show the plaintiff to have been damnified, it was held that the instrument was more than a bond of indemnity and that the breach was well assigned by showing that the debt was not paid at the day. In the matter of Negus, 7 Wend. 503, there was a covenant among others by one partner to another to pay the debts of the firm, and also to indemnify *281tbe obligee. In answer to the objection that it was simply a bond of indemnity and that therefore the obligee mnst have shown that he had been damnified by the payment of debts which the obligor assumed to pay, the court observes that, although a covenant to indemnify followed the covenant to pay the debt, it did not alter the force and effect of the proceeding ; that the covenant to pay the debts was an affirmative covenant to do a certain thing — to pay certain sums of money, and that it was no defence to the action to say the plaintiff had not been damnified. If the condition of the bond stipulates for the performance of any particular act, performance of that act must be averred, and in an action on such a bond non damnificabas is not a good plea. (Combs v. Newton, 4 Black. 121; 20 John. 161; see also Woods v. Rowan & Coon, 5 Johns. 43; 3 Cowen, 332.)
As to the measure of damages in this case, if the plaintiff is entitled to recover, we see no reason why he should not recover the sum due by the bond.' Of course, if the bond has been paid in part, or otherwise satisfied, the defendant will be entitled to the benefit of such payment or satisfaction. The presumption is that the plaintiff gave full consideration for the bond, and if it is not discharged the defendant should pay the amount of it. The defendant being a copartner and liable to partnership creditors, notwithstanding his bond to the plaintiff, if the situation of the plaintiff is such or if there are any circumstances that would make it just to do so, the court, on the trial, would, in rendering judgment, see that the defendant was made safe in paying the judgment; or it might be a ground for an injunction and relief in equity.
The judgment will be reversed and the cause remanded;
the other judges concurring.
