The noble lord has stated that he will not recall the marines. I would beg to remind your lordships, and the noble viscount in particular, of this fact--that the marines are properly the garrisons of his majesty's ships, and that upon no pretence ought they to be moved from a fair and safe communication with the ships to which they belong. The noble lord states, that he is responsible, and that he will take upon himself the responsibility. I have commanded his majesty's armies, and have incurred as many risks, and faced more difficulties than, I hope, the noble lord will ever have to encounter. I have been engaged in hostilities of this description, where co-operation was carried on upon the coast; and though I certainly would do as much for the service, and I believe I may say, have done as much for the service, as the noble lord, yet I would not venture, and have never ventured, to put any corps whatever in co-operation with the Spaniards, or in any situation whatever in which the detached troops could not communicate with the corps from which they were detached; and, above all, upon the sea-coast, where the troops detached could not hold communication with the ships. The first order to each of these detachments was, to keep the communication with their ships. The loss of 400 or 500 marines may not materially involve the honour of this country, but the lives of the men ought not to be endangered, as they must be, if care be not taken that they should have a communication with a point of safety, without some very extraordinary cause. We hear of the operations of the marines with the Austrians. But the Spanish troops, and particularly the British legion, are not the Austrians. I cannot consider this corps of General Evans to be in a state of discipline and subordination, such as a body of troops ought to be in, with which his majesty's marine forces ought to be connected. They have suffered very considerably; their losses have been great, and have affected their subordination, their good order and discipline, particularly in the presence of an enemy. A disaster or panic may occur among the best troops; but among such, order can be re-established. It does not appear that these are in the state in which they ought to be, to render it safe to co-operate with them. No efforts of their officers can, in such cases, have any effect upon them. _April_ 21,1837. * * * * * _Intervention, if at all, should be on a National Scale_.
