p. 56opinion of this court. Of what damages did we order an equal division ? There were no others asserted or claimed than those sustained by the libellant. We do not say that a cross-libel is always necessary in a case of collision in order to enable claimants of an offending vessel to setoff or recoup the damages sustained by such vessels, if both be found in fault. It may, however, well be questioned whether it ought not to appear in the answer that there were such damages. It is undoubtedly the rule in admiralty that where both vessels are in fault the sums representing the damage sustained by each must be added together and the aggregate divided between the two. • This is in effect deducting the' lesser from the greater and dividing the remainder. But this rule is applicable only where it appears that both vessels have been injured. If pne in fault has sustained no injury, it is liable for half the damages sustained by the other, though that other was also in fault. And, so far as the pleadings show, that is the case now in hand. But, without deciding that the claimants of the Sapphire were not at liberty to show that their ship was damaged by the collision, and to set oft* those damages against the damages of the libellant, it must still, we think, be held- they have waived any such claim. If bur mandate was not a direction to enter a decree for one-half the damages of the libellant, if its -meaning was that a decree should be made dividing the aggregate of loss sustained by both vessels, which may be conceded, it was the duty of the respondents •to assert and to show that the Sapphire had been injured. This they made no attempt to do. When the cause went down they neither asked to amend their pleadings, nor to offer further proofs, nor to have a new referente to a commissioner. So far as the record shows, they set up no claim, even then,-or at any time before the .final decree, that there were any other damages than those which the libellant had sustained. It is not competent for them to make such a claim first in this court. We cannot say, therefore, the court below did not decree iu accordance with our mandate.
The appellants further complain that it was erroneous to
