At four bells in the afternoon watch the wind had fined down to such an extent that the frigate was making no more than a bare four knots through the water, although we had by this time got up the fore-topgallant and royal-masts again and were once more under all plain sail; while, as for the two Indiamen, built as cargo-carriers rather than for speed, they appeared to scarcely have steerage-way, and seemed to maintain their luff only with the utmost difficulty--indeed, there were times when they fell so broad off as to present their full broadsides to us.  But although their capture might now be regarded as practically certain, they were evidently not disposed to yield without making some sort of a struggle for liberty, for they were on opposite tacks, one of them having gone about; the idea, of course, being to separate and widen their distance as much as possible in the hope that by so doing one of them at least might escape, even if the other were captured.  Captain Vavassour, however, did not allow these tactics to disconcert him in the least; he fixed upon one of them as the object of his pursuit--altogether disregarding the movements of the other, meanwhile--and devoted all his efforts to close with her, with the result that by two bells in the first dog-watch we were within gunshot of our quarry, when a shot was pitched across his forefoot as a gentle hint to him to heave-to.  But he declined to take the hint, and it was not until we sent a shot whistling between his masts that the sturdy old Mynheer could be convinced of the impossibility of escape, when he hoisted his colours to the peak only to instantly haul them down again and back his mainyard in token of surrender.
