We find mentioned in the paper of this day, the arrival of the late U. States frigate President at Plymouth; they barely mention that she had arrived at that place, and that she was captured by the Endymion, but the circumstances of the capture they very prudently left out, as reflecting no honor on the captors. Capt. Shortland had two men committed to close confinement, who had been accused of drawing money from the Directors of Greenwich Hospital, under assumed names. On the fourth, a circumstance occurred, which may lead to the recital of other circumstances, which many to whose hand this work may come, may be inclined to doubt the veracity of; but I can appeal, not only to those who have certified this work, but to nearly six thousand of my fellow prisoners, who upon their solemn oath can attest to the truth of what is herein contained. During the whole of this day the prisoners remained without bread, and the captain of the prison gone to Plymouth: we were obliged to subsist on the four and a half ounces of beef, and the soup made of it; we demanded of the contractor the reason of our not drawing our usual allowance of bread; he answered, that it could not be obtained till to-morrow; we waited as patiently as our feelings would allow, till the expiration of thirty-six hours from the time we had received the last bread, when hunger became so pressing, that it drove us to a state of desperation, and we could no longer endure it, as the whole allowance was scarcely sufficient to sustain life. At dusk in the evening, we again demanded the reason of our not receiving our allowance of bread as usual, as the store-house we well knew contained a sufficiency of both hard and soft bread. The contractor’s clerk informed us, that a quantity of damaged hard bread, which had been kept in reserve for times of extreme necessity, now remained on hand, and that unless we would accept of one pound of that in lieu of the pound and a half of soft bread allowed by the Transport Board, until all they had was expended, he should not serve us with any bread, until Capt. Shortland returned from Plymouth.
