Summary judgments were entered against the United States and in favor of the defendant, Bissett-Berman Corporation, and others in actions filed by the United States as plaintiff, under 28 U. S.C. § 1345, to recover damages for breach of contract to make certain marine installations. The United States appeals from those summary judgments for the defendants. We affirm.

On June 11, Í964, the Navy Electronics Laboratory (NEL) invited a proposal for the design, fabrication, installation at sea, and operational testing in situ of what was described as a “Deep-Moored Vertical Hydrophone Array with Radio Telemetry Line.” The invitation contemplated a proposal to award two contracts to the same contractor. First, a research and development contract covering the design, fabrication and interim testing of the array; and second, a time and material contract covering the installation and checkout at installation sites.

Bissett-Berman Corporation (BBC) was awarded both contracts. The manufacturing contract was completed and after dockside checkout was approved, BBC proceeded with the installation of the system at sea at a point approximately 18 miles off Point Arena, California. For this purpose BBC chartered a ship, the M/V Nesco I from Western Offshore Drilling & Exploration Company (WODECO), a division of Pike Corporation of America. The system was installed on or about April 27, 1967. In place it consisted of surface marker buoys to which was attached a polypropylene line leading to a subsurface buoy some 1,000 feet below the surface. From that point an armored cable descended 5,000 feet more to the bottom. Although anchored at the bottom, the cable thereafter extended 7,000 feet along the bottom to a point at which it was again anchored. It then was brought to the surface where it attached to the transmission buoy. The hydrophone array was attached to the descending cable. Thus, on the surface the marker buoys and the transmission buoy were 7,000 feet apart although connected by a continuous line and cable beneath the surface.

Approximately 30 days after initial installation the transmission buoy broke loose and the cable to which it was attached dropped to the floor of the ocean. This buoy was recovered, repaired, and BBC was instructed by the United States to reinstall the system. The plan was to recover the system by locating the two marker buoys, which established the other end of the system, and by pulling these on the ship and thereafter the cable to which they were attached. This procedure would result in the recovery of the hydrophone array and the rest of the cable to which the transmission buoy had been attached at the opposite end of the installation. The transmission buoy would then be reattached to its end of the system and the apparatus replaced in the sea.

The marker buoys on the surface were located and pulled aboard. Because it was difficult to haul in the line, Mr. Wyborny, the BBC employee in charge of the operation, instructed the captain by hand signal to back the ship so as to create slack in the line. Too much slack was created quickly however permitting the polypropylene line to become entangled in the propellers. During an attempt to splice the line around the tangle, it parted and all was lost beneath the surface.

As a result of the loss of the hydrophone array, the United States filed this action asserting several claims against BBC. The first was for breach of the contracts claiming damages; second, for breach of warranty that the system was free from defects and conformed to specifications; third, for the amount of insurance coverage procured by BBC to protect and indemnify BBC against liability for loss or damage to government property in BBC’s possession or control; fourth, for gross negligence tantamount to willful misconduct or bad faith on the part of BBC’s representatives in their handling of government property. The total amount sought was $742,561.50.

In addition, and in the same action below, the United States asserted several claims in separate causes of action against Pike, owner of Nesco I, and WODECO, operator of Nesco I, in personam and against Nesco I in rem. The first cause of action was for damage caused by the negligent navigation of the vessel resulting in the fouling of the polypropylene line and the loss of the array; the second was for damage caused by negligence of the crew.

Finally, the United States added a fifth and sixth cause of action against BBC sounding in contract, asserting that to the extent that BBC had failed to provide in its subcontracts with the divers, (fifth cause of action), and with the vessel and its owners, (sixth cause of action), for liability of the subcontractors to the government and had by subcontract relieved the subcontractors of liability for loss and destruction of the array, BBC was liable to the United States. In support of this theory, the United States relied upon a paragraph of the Pike and WODECO subcontract which provided that BBC personnel aboard the ship would be in complete charge of the installation thus making the Pike and WODECO personnel on the ship “borrowed servants” of BBC and exonerating them from direct liability according to the government’s theory.

Under Rule 56(c) Fed.R.Civ.P. a summary judgment shall be rendered forthwith,

The affidavits shall be made on personal knowledge,

Thus, the district court does not try issues of fact. Its function is to determine whether an issue of fact exists which might be material to the determination of an issue in the case. On review it is our function to determine “whether there is any genuine issue of material fact underlying the adjudication, and, if not, whether the substantive law was correctly applied.” 6 Moore’s Federal Practice (2d ed.) ¶ 56.27 [1] at 2973; Vickery v. Fisher Governor Co., 417 F.2d 466 (9th Cir. 1969).

The issue upon which the district court decided the case in favor of BBC was that all of the claims asserted by the United States against BBC in the first four causes of the First Amended Complaint were barred by a Stipulation of Settlement executed between the parties on December 22, 1969.

After the loss of the array and before the action was filed in the district court, the contracting officer of the government directed BBC to pay certain sums to it as damages for the loss of the array and announced that the government was not obligated to pay the balances due under the contract. BBC appealed both decisions to the Armed Services Board of Contract Appeals (ASBCA). The pleadings in those cases raised the same legal issues as are set out in the first four causes of action of the government’s complaint in this litigation. During the course of preparation for the trial of those appeals and following the pretrial hearing, attorneys for the government instituted negotiations looking toward a settlement of the two cases which had been consolidated. After a number of conversations and meetings concerning the settlement an agreement was reached and a stipulation prepared, but a representative of the government refused to approve it and took it to Washington for further review and consideration. Almost two months later negotiations were resumed, a Stipulation of Settlement was prepared by the government and signed by the parties. It carried the caption of the ASBCA action, identified the two cases on appeal and was filed in the case.

On December 29, 1969, an Order of Dismissal with Prejudice was entered in the cases based upon the Stipulation of Settlement which had been filed. The order carried the caption of the two cases and showed the appearance of Murray H. Marker, Esq., Counsel, Navy Purchasing Office and Martin L. Glass, Esq., Assistant Counsel, appearing for the government, and Gerald N. Gordon, Esq., appearing for the appellant. It was signed by Joseph B. Kennedy, Jr., for the Board and bore the signed concurrences of four other members.

The government contends that the stipulation is a nullity because there was no meeting of the minds and because the attorney who signed had no authority to do so. As to the meeting of the minds, the language of the stipulation appeared perfectly clear to the trial court and appears entirely so to us. The later discovery by the government of its unilateral mistake that a payment had been made so that the government should have reduced its settlement figure accordingly does not prevent a contract under the facts of this case. Heifetz Metal Crafts, Inc. v. Peter Kiewit Sons’ Co., 264 F.2d 435 (8th Cir. 1959); Bowser, Inc. v. Hamilton Glass Co., 207 F.2d 341 (7th Cir. 1953); United States v. Jones, 176 F.2d 278, 285 (9th Cir. 1949). There was no showing of mutual mistake or of fraud on the part of BBC.

As to the authority of Mr. Marker to sign the stipulation instead of the contracting officer, Mrs. Barger, it would appear that there is more involved here than the execution of a contract. The parties were in fact settling a law suit. The stipulation was prepared under the caption of the case for filing therein, and the Order of Dismissal showed that Mr. Marker and Mr. Glass both appeared for the government for the purpose of the entry of the order. The court and the opposite parties were entitled to assume that the government attorneys had the authority to obtain the Order of Dismissal. It was not conditional. Mr. Marker stated in his affidavit filed in the trial court that:

Appellant next contends that the stipulation was a nullity because the “money to effectuate the settlement could only have been obtained by contract modification” (Appellant’s Opening Brief at 39), and Mr. Marker, the attorney who signed the stipulation was not a contract officer and had no authority to sign a contract modification. The trial court did not regard the stipulation as simply a contract modification, nor do we. It may have had an effect on a dispute arising out of a contract, but it was in fact and in law the settlement of claims in litigation before an administrative body constituted by law to make an adjudication. As a result of the stipulation and relying upon the representation of authority of the two attorneys for the Navy to act on behalf of their clients the Board dismissed the appeal with prejudice. Although the appellant contends the attorneys who represented the government in the negotiation of the contract modification had no authority to bind their clients to a contract modification, the government has not suggested that Marker and Glass were not its attorneys before the ASBCA and authorized to appear and act for it. The trial court was correct in its ruling in favor of BBC on the first four causes of action of the Amended Complaint.

The Stipulation of Settlement reserved to the government the right to assert the fifth and sixth causes of action against BBC. These were based purely on breach of contract, alleging that BBC had failed to enforce the liability of the divers (fifth cause of action) and that BBC had omitted from the subcontracts provisions which would have protected the government against loss of or damage to its property in the possession of BBC’s subcontractors (sixth cause of action). The court granted summary judgment in favor of BBC on both causes of action.

Looking to the fifth cause of action, the contention is that a provision should have been inserted in the contract between BBC and the divers that the latter were absolutely liable for the loss of any government property in their possession. The district court, however, expressly found that BBC “never gave possession or control of the hydrophone array system to either Western Offshore Drilling and Exploration Co. Division of Pike Corporation of America or the Rogers Diving Service.” At the time of the loss of the system it had already been implanted in the ocean by BBC and the effort was to recover it so that the transmitting buoy could be reattached to the other end. Until recovered it was in no one’s possession. The affidavits in support of the motions for summary judgment also support the court’s finding that the divers never had possession and control of the array. There was no genuine issue of fact upon this point.

The sixth cause of action is based upon the same theory. The government relies upon Clause 5(f)(1) of the installation contract which provides:

The same finding of the trial court which forecloses the fifth cause of action stands as a bar to the government in the sixth. In addition, the Pike & WODECO contract' contained the following provision:

It appears to be appellant’s argument that this provision in the contract between BBC and WODECO will release WODECO from liability to the government. Actually, a literal reading of the clause discloses that it does not purport to release WODECO from liability to the United States if one does exist. Clause 5(f)(1) does not require the prime contractor to make its subcontractors “absolutely liable” to the government. It requires a provision that the subcontractors return government property if they have any. Here they had none. If the subcontractors became liable in negligence to the government, the cause of action thus created could not be contracted away without the government’s consent. Unless released by the government, it would still remain. The W. C. Block, 71 F.2d 682 (2nd Cir.), cert. denied sub nom. Cornell Steamboat Co. v. Scholl, 293 U.S. 579 , 55 S.Ct. 91 , 79 L.Ed. 676 (1934); George Bohannon Transportation, Inc. v. Davis, 323 F.2d 755 (10th Cir. 1963).

The prime contractor, BBC, could have provided its own ship and crew and thereby would have become responsible for the negligence of its own servants and employees, if in fact such liability were established. It did not do this. It contracted with Pike, WODECO and the divers, but retained all supervision and control over their activities. We find nothing in the government contract which proscribes this, either as to Pike, WODECO or the divers.

Finally, the government asserts a direct cause of action against defendants Pike, WODECO and Nesco I in rem for maritime tort in the operation and navigation of the vessel, and a second cause of action against the same defendants based upon the negligence of the crew (the divers) in handling the line of the array whereby it was lost.

As to the claim based upon a maritime tort in the operation and navigation of the vessel, the subcontract with BBC provides that BBC personnel will be in complete charge of the operation. Notwithstanding the findings which support the fact of supervision and control in BBC and not in Pike, WODECO or the vessel’s crew, the government contends that this is a maritime tort. It likens the asserted maritime liability to the liability of the ship and owner for collision with another vessel even though the maneuvering of the vessel is under the control of a “compulsory pilot.”

The difficulty with the “compulsory pilot” analogy is that the facts as shown by the affidavits, the contracts and the findings of the trial court, establish that the “compulsory pilot” was BBC. It was in complete control of the salvage operation and exercised that control by signals to the master to direct the backing of the ship when the line became fouled in the propeller. Yet BBC as the operator was not liable in personam because its contract with the government made it liable only for damage or loss as a result of willful misconduct. No such showing was made. In addition, the settlement agreement released BBC from claims for willful negligence which was the only negligence alleged (fourth cause of action). Here then the “compulsory pilot” has been released and the question is whether an in rem maritime claim on the vessel may be imposed nonetheless. We are of the opinion that it cannot and sustain the trial court’s holding. Only two cases were cited by the government on the point. One of them, Homer Ramsdell Transportation Co. v. La Compagnie Générale Transatlantique, 182 U.S. 406 , 21 S.Ct 831 , 45 L.Ed. 1155 (1901), is not in point because it is an action at law and not in admiralty. The authority of The China, 74 U.S. (7 Wall.) 53 , 19 L.Ed. 67 (1868), for the proposition that an in rem libel against the ship may be maintained when an action against its owner or operator can not has been weakened if not destroyed by subsequent cases. In Guzman v. Pichirilo, 369 U.S. 698 , 82 S.Ct. 1095 , 8 L. Ed.2d 205 (1962), where the question was liability based upon unseaworthiness, the Court declined to clearly decide the issue. See Reed v. The Yaka, 373 U.S. 410 , 83 S.Ct. 1349 , 10 L.Ed.2d 448 (1963) (where the Court also declined to decide the question). In the courts of appeals it appears clear that most, if not all, have held that in personam liability is a sine qua non for in rem liability against the ship. Ramos v. Beauregard, Inc., 423 F.2d 916 (1st Cir.), cert. denied, 400 U.S. 865 , 91 S.Ct. 101 , 27 L. Ed.2d 104 (1970); Alcoa Steamship Co. v. Rodriguez, 376 F.2d 35 (1st Cir.), cert. denied, 389 U.S. 905 , 88 S.Ct. 215 , 19 L.Ed.2d 219 (1967) ; Noel v. Is brandtsen Co., 287 F.2d 783 (4th Cir.), cert. denied, 366 U.S. 975 , 81 S.Ct. 1944 , 6 L.Ed.2d 1284 (1961).

Judge Learned Hand has been cited as being on both sides of the controversy. See Noel v. Isbrandtsen Co., supra at 786 n. 6. In Burns Co. v. The Central R. R., 202 F.2d 910, 912 (2nd Cir. 1953), he refers to the idea of the ship as a tortfeasor as difficult to explain “on any other theory than a vestigial devolution out of the notion that anything that moves and kills a man shall be deodand to the king.”

Even in The China, supra, which seems to be the only clear decision that the vessel itself can be libeled absent in personam liability, there must be a showing that the vessel is a “wrongdoer.”

In the present case the undisputed facts fail to indicate that the navigation was negligent or careless. We can find no rational basis to assume that because the vessel was moving it was at fault under the circumstances disclosed and decline to adopt the in rem liability theory where in personam liability does not exist.

Here, the officer in charge was under the direct and exclusive command of BBC and acting at the time under BBC’s supervision and control. A release given to BBC would therefore include the in rem liability of the ship. The Queen of the Pacific, 180 U.S. 49 , 21 S.Ct. 278 , 45 L.Ed. 419 (1901); The Elizabeth M. Miller, 3 F.Supp. 171, 172-173 (W.D.N.Y.1932). The other theory of liability urged by the government to support the liability of the owner of the Nesco I is that fault is presumed against a moving vessel which collides with a properly moored ship'— the doctrine of res ipsa loquitur. Granting that the doctrine is well recognized in admiralty, it poses no new concept of tort law. It is an inference of negligence which is raised because it is the type of accident that does not ordinarily occur absent someone’s negligence, and the evidence to prove it is circumstantial. Here, however, we have more than the inference or presumption to look upon. We have the affidavits of those at the scene which stated in detail how the accident came about. It was a difficult and delicate maneuver under adverse circumstances to attempt to secure a line and put it aboard and onto a reel where it could be hauled up from 6,000 feet. There is no room in face of the affidavits and reports, including the Allen reports submitted by the government, to rely on presumptions. Explanation abounds as to just what happened and there is no material difference among those who observed. On the basis of the undisputed facts we believe that the trial court’s order was entirely proper.

Under the circumstances disclosed by the affidavits and expressly found by the trial court, the crew of Nesco I was “loaned to” or were the “borrowed servants” of BBC. Thus BBC and not Pike and WODECO is responsible for the action of Nesco I and its crew during the salvage operations. The borrowed servant doctrine is recognized and followed by this court. Denton v. Yazoo & Mississippi Valley R. R., 284 U.S. 305 , 52 S.Ct. 141 , 76 L.Ed. 310 (1932); United States v. N. A. Degerstrom, Inc., 408 F.2d 1130, 1133 (9th Cir. 1969); McCollum v. Smith, 339 F.2d 348 (9th Cir. 1964).

We have examined the pleadings and the affidavits on file and agree with the trial court that there is no genuine issue of material fact and that the trial court has correctly applied the substantive law involved. Accordingly, the judgment is affirmed.

. Clause 5(f)(1) of the contract provided in pertinent part that: “The contractor shall not be liable for any loss of or damage to the Government Property, or for expenses incidental to such loss or damage, except that “(i) which results from willful misconduct or lack of good faith on the part of anyone of the Contractor’s directors or officers, or on the part of any of his managers, superintendents, or other equivalent representatives . . . . ” C.T. at 70. .
