Another explanation of the failure to make a thoroughly successful commercial speculation of the capture of Cadiz, is to be found in the rivalry between the chiefs. To this there was a chivalrous side. The eagerness with which Howard and Essex, Raleigh and Lord Thomas Howard, strove to outstrip one another for the foremost place in driving back the King of Spain's galleons, and storming his city, makes a very gallant story. They behaved much after the manner to be expected of spirited sixth-form boys. In that there was nothing dangerous to the interests of the service. But this emulation had another side, which is only to be accurately described by the less honourable name of rivalry. Essex and Raleigh were both courtiers who were endeavouring to excel one another in the favour of the queen by outdoing one another in the flatteries Elizabeth loved. They had come to open hostility already, and having been reconciled, they of course hated one another mortally. At Cadiz the evil consequences of their hostility were hardly apparent. But there was enough of it to prevent the campaign of 1596 from being as fully successful as it might have been. There was in the greater Elizabethan enterprises unity of sentiment and a vigour of energy which produced success in the main, but there was hardly what in the full sense of the word is called discipline. In addition to the rivalry between the leaders, there was a rivalry between the different types of men. The sailor and the sailor officer were opposed to the soldier. The latter grew impatient when the former endeavoured to overbear him by appeals to seamanship, and the conditions of war at sea which the military man only vaguely understood, while the sailor was apt to think himself sacrificed to the soldier.
