Magoun, a subcontractor doing steel erection in the construction of a school in Hyde Park, seeks in this action of contract to recover from the insurance company (Liberty) his expenses in defending an action of tort brought against him by the administratrix of the estate of one Barker. The declaration (see fn. 3, infra) in that action alleged negligence causing Barker’s death and conscious suffering. The present case, before us on Liberty’s bill of exceptions, was heard in the Superior Court upon a statement of agreed facts. Liberty requested a ruling that “ [o]n the facts stated, as a matter of law, there must be a finding for” Liberty. The trial judge denied this request and ordered judgment for Magoun in the sum of $3,526.48. Liberty has argued exceptions to the judge’s action.
On December 23,1950, Liberty issued a “schedule general liability policy (manufacturers’ and contractors’ form)” to Magoun. Coverage A of this policy, in effect when Barker was killed, bound Liberty to “pay on behalf of . . . [Magoun] all sums which . . . [Magoun] shall become legally obligated to pay as damages because of bodily injury . . . including death . . . resulting therefrom . . . caused by accident and arising out of the hazards hereinafter defined.” Under the heading “Definition of Hazards,” division 1 of the policy reads, “premises — operations — The . . . use of premises and all operations necessary or incidental thereto.” 1 Under the heading “Exclusions” ap *679 pears a provision (for convenience referred to as the “loading exclusion”) which reads, “This policy does not apply: (a) under division 1 of the [definition of [h]azards, to the . . . use, including loading or unloading, of ... (2) automobiles while away from such premises or the ways immediately adjoining . . ..” The word “automobile” is defined as “a land motor vehicle, trailer or semitrailer,” with certain exceptions not relevant. This definition plainly includes a truck. The policy, under the heading, “Defense, Settlement, Supplementary Payments,” contained also an agreement by Liberty to defend Magoun, the pertinent portion of which appears in the margin. 2
On May 22, 1951, “Magoun was engaged in removing steel joists from railroad cars ... on premises [at 1670 Hyde Park Avenue] owned and controlled exclusively by” a railroad. “The . . . [railroad] premises properly were being used by Magoun in loading the steel joists onto trucks to be used in connection with the erection of the . . . [s]chool. The . . . [railroad] premises were not adjoining premises of Magoun,” whose employees were doing the unloading and placing the joists on Magoun’s trucks and “on a truck owned by C. E. Hall & Sons, which truck and a driver were hired by Magoun to help fulfill his job as a subcontractor. . . . Barker, the operator of the . . . [Hall] truck, was killed on the . . . [railroad] premises . . . when joists, which were loaded on the . . . [Hall] truck by employees of Magoun, fell upon him from that truck.”
Prompt oral and written notice of the accident was given to Liberty. On August 29, 1951, Liberty wrote to Magoun, “[W]e are handling this claim under full reservation of rights under your policy contract with us. Our investigation to date indicates that . . . Barker’s death arose out of the loading of the 0. E. Hall truck. Tour policy contract
*680
with us does not provide protection to you under these circumstances.” The letter then quoted the loading exclusion and continued, “Please forward promptly . . . any correspondence or legal papers which may be served on you in order that we may review them to be sure that we give you all the protection to which you are entitled under the terms of your policy of insurance.” Subsequently, “an action of law

was brought by . . . [Barker’s] [administratrix . . . against Magoun and others. Liberty . . . notified Magoun that it was willing to undertake the defense of the action under the reservation set forth above. Magoun was unwilling to have Liberty represent it under the terms of that reservation and so notified Liberty. As a result, Magoun hired his own counsel to handle the defense of the . . . tort action. Counsel for Liberty thereafter cooperated with the counsel retained by Magoun in the defense of the . . . tort action,” in which it “was found . . . that the employees of Magoun negligently caused the death of . . . Barker .... The tort action resulted in a final judgment on October 6, 1958, for Magoun on the ground that the

common employment’ doctrine . . . [see G. L. c. 152, § 18, as amended through St. 1939, c. 93; see also
McPadden
v.
W. J. Halloran Co.
Liberty contends (a) that the accident occurred in circumstances within the loading exclusion, and (b) that Liberty should not be required to pay Magoun’s legal expenses *681 in view of Liberty’s offer to defend Magoun in the tort action under reservation of rights, Magoun’s refusal of that offer, and Liberty’s surrender to Magoun of control of de-fence of the tort action.
Liberty’s basic, initial liability to defend under its agreement to do so (see fn. 2,
supra)
is determined by the allegations of the declaration in the tort action. Liberty was not required to defend unless the policy would bind it to indemnify Magoun if Barker’s administratrix should prevail upon the allegations of the declaration. See
Fessenden School, Inc.
v.
American Mut. Liab. Ins. Co.
The case presents a question not decided in
Salonen
v.
Paanenen,
Liberty here made a reservation by its letter of August 29,1951, before the tort action was commenced (see
Marvel Heat Corp.
v.
Travelers Indem. Co.
We are thus confronted with the question whether the insurer must pay the insured’s legal expenses, if the insurer (a) has a substantial ground for disclaimer of liability, (b) asks for the insured’s consent to its defending under a reservation of right, (c) is denied that consent, and (d) then yields control of the defence to the insured at the latter’s request. Our cases have not dealt with this precise point.
The covenant to defend (see fn. 2,
supra)
does not spell out in any great detail the insurer’s obligation in such cir
*684
cumstances. It, however, must be taken to require the insurer, to the extent that the facts permit, to defend the insured at least in good faith and without negligence. See
Murach
v.
Massachusetts Bonding & Ins. Co.
Where the insured’s interest in controlling tort litigation against him conflicts with the similar interest of the insurer, the insured may have good cause to ask that he be represented by counsel independent of the insurer. The insurer, on the other hand, reasonably may be reluctant to entrust its possible obligation to indemnify to counsel not of its own selection, particularly where, as here, the obligation to defend exists largely, if not entirely, only because the declaration of the tort plaintiff is not stated in a manner revealing that the claim is not within the policy coverage. See note, 68 Harv. L. Rev. 1436, 1448; note, 2 Stanford L. Rev. 383, 387-388; annotation, 49 A. L. R. 2d 694, 700-703. See also Appleman, op. cit. § 4694.

It was the recognition of this type of potential clash of interests, which led us in
J. D’Amico, Inc.
v.
Boston,
*685
In the present case, in view of the possible divergence of interests, the parties have at least acquiesced in defence of the insured by counsel retained by him and Liberty has cooperated in that successful defence. The agreed facts reveal no agreement or reservations concerning the cost of the independent defence. Because Liberty could have included in the covenant to defend explicit provisions concerning the cost of defence in various situations some of which have been mentioned above, we think that uncertainty should be resolved against the insurer. See the
D’Amico
case,
Exceptions overruled.
Notes
Operations classifications specified included “Iron, or Steel Erection — frame structures, iron work on outside of buildings including erecting or repairing balconies, fire-escapes, railings, staircases, coal chutes or fireproof shutters” (Code No. 3452) and Iron or Steel Erection — N[ot], O[therwise]. Classified], (Code No. 5057). Under an extension schedule heading “Division 1. Operations Location of Project,” among Massachusetts locations listed was “Elementary School, Henry Grew District Hyde Park.”
This provision reads in part, "As respects the insurance afforded by the other terms of this policy the company shall: (a) defend any suit against the insured alleging such injury . . . and seeking damages on account thereof, even if such suit is groundless, false or fraudulent; but . . . [Liberty] may make such investigation, negotiation and settlement of any claim or suit as it deems expedient . . .
“The declaration in the tort action against Magoun contained two counts, one . . . for conscious suffering and the other for . . . [Barker’s] death . . .. The allegations concerning liability in each of the two counts were . . . ‘And the plaintiff says that on . . . the 22nd day of May, 1951, the defendant, his agents or servants, was engaged in the handling of a load of steel at the freight depot in Hyde Park . . . that . . . while . . . [Barker] was lawfully on . . . [the] premises and in the exercise of due care, the defendant, his agents or servants, so negligently and carelessly handled said load of steel that by reason thereof, the steel fell on” Barker (emphasis supplied).
