The accounts from Spain were indeed most serious. It is the misfortune of men of superior military ability that their subordinates are generally failures when trusted with independent commands. Accustomed to obey implicitly the instructions of their chief, they have done what they have been told to do, and their virtue has been in never thinking for themselves. They succeed, and they forget why they succeed, and in part attribute their fortune to their own skill. With Alexander's generals, with Caesar's, with Cromwell's, even with some of Napoleon's, the story has been the same. They have been self-confident, yet when thrown upon their own resources they have driven back upon a judgment which has been inadequately trained. The mind which guided them is absent. The instrument is called on to become self-acting, and necessarily acts unwisely. Caesar's lieutenants while under his own eye had executed his orders with the precision of a machine. When left to their own responsibility they were invariably found wanting. Among all his officers there was not a man of real eminence. Labienus, the ablest of them, had but to desert Caesar, to commit blunder upon blunder, and to ruin the cause to which he attached himself. Antony, Lepidus, Trebonius, Calvinus, Cassius Longinus, Quintus Cicero, Sabinus, Decimus Brutus, Vatinius, were trusted with independent authority, only to show themselves unfit to use it. Cicero had guessed shrewdly that Caesar's greatest difficulties would begin with his victory. He had not a man who was able to govern under him away from his immediate eye.
