Just as every thing was arranged, ready to march against Capua, the event which his lordship had anticipated in his letter to Earl Spencer actually occurred. A peremptory order arrived, on the 19th, from Lord Keith, directing him to detach, immediately, from the Island of Sicily, the whole of his squadron--or such part, at least, as might not be necessary in that island--for the protection of Minorca. Lord Nelson, however, well knowing, that Lord Keith, at the time of sending this order, could not be informed of the change of affairs in the kingdom of Naples, where all the marines, and a considerable body of seamen, were now landed, in order to drive the French scoundrels out of the kingdom--which was likely, he said, with God's blessing, to be very soon effected, when a part of the squadron should be instantly sent--he thought it right, till the French were all driven from Capua, not to obey his lordship's order for sending down any part of the squadron under his command. After stating these reasons, as his apology for thus acting, his lordship thus concludes--"I am perfectly aware of the consequences of disobeying the orders of the commander in chief; but, as I believe the safety of the kingdom of Naples depends, at the present moment, on my detaining the squadron, I have no scruple in deciding, that it is better to save the kingdom of Naples, and risk Minorca, than to risk the kingdom of Naples, and save Minorca. Your lordship will, I hope, approve of my decision." Though Lord Nelson's heroic bosom could by no means fail to be violently agitated on this very alarming occasion, his resolution was not to be shaken by any consideration of personal suffering: had the refusal been attended with the certain loss of life, he would not have consented to part with a single ship; such was the inflexible firmness of this invincible man, when his determination was once fixed. He did not, however, set danger at defiance; though he so little regarded it's weight, when placed in the scale which opposed his own conscious sense of duty. Desirous to be duly understood, and to obtain the indemnity of which he could not but consider himself as worthy of receiving, he had ventured to hope for Lord Keith's approbation of his conduct. He judged it right, however, to be prepared against the worst that could happen, by immediately addressing Earl Spencer, also, in a private letter on the subject; as well as the Admiralty in general, through their secretary, Mr. Nepean. These valuable documents, at once self-criminating and exculpatory, are finely characteristic of his lordship's firmness, sensibility, and honour. "Foudroyant, Naples Bay, 19th July 1799.
