At the same time that the firing was going on in the square, a cross fire was also kept up from several of the platforms on the walls round the prison where the sentries stand, by straggling parties of soldiers who ran up there for that purpose. As far as this fire was directed to disperse the men assembled round the breach, for which purpose it was most effectual, it seems to stand upon the same ground as that in the first instance in the square. But that part, which it is positively sworn was directed against struggling parties of prisoners running about the yards and endeavoring to enter in the few doors which the turnkeys, according to their usual practice, had left open, does seem, as stated, to have been wholly without object or excuse, and to have been a wanton attack upon the lives of defenceless, and at that time unoffending individuals. In the same, or even more severe terms, we must remark upon what was proved as to the firing into the door-ways of the prisons, more particularly into that of No. 3 prison, at a time when the men were in crowds at the entrance. From the position of the prison and of the door, and from the marks of the balls which were pointed out to us, as well as from the evidence, it was clear this firing must have proceeded from soldiers a very few feet from the door-way; and although it was certainly sworn that the prisoners were at the time of part of the firing at least, continuing to insult and occasionally to throw stones at the soldiers, and that they were standing in the way of, and impeding the turnkey, who was there for the purpose of closing the door, yet still there was nothing stated which could in our view at all justify such excessively harsh and severe treatment of helpless and unarmed prisoners, when all idea of escape was at an end. Under these impressions we used every endeavor to ascertain if there was the least prospect of identifying any of the soldiers who had been guilty of the particular outrages here alluded to, or of tracing any particular death at that time to the firing of any particular individual, but without success; and all hopes of bringing the offenders to punishment should seem to be at an end. In conclusion, we, the undersigned, have only to add, that whilst we lament, as we do most deeply, the unfortunate transaction which has been the subject of this inquiry, we find ourselves totally unable to suggest any steps to be taken as to those parts of it which seem to call for redress and punishment. (Signed) CHARLES KING, FRAS. SEYMOUR LARPENT. LONDON, 18th April, 1815. SIR, At the request of Lord Castlereagh, we have had interviews with him and Mr. Goulburn on the subject of the transportation of the American prisoners now in this country, to the United States, and of the late unfortunate event at the depot at Dartmoor.
