Sir Howard sat in Parliament for Liverpool during Sir Robert Peel’s last administration, and spoke and voted on all occasions like a sound yet thoughtful Conservative. In 1847 he retired from the House of Commons, and thenceforth applied his energies to the service of the country as a writer on professional and scientific subjects. His treatise on ‘Naval Gunnery’ had already gone through several editions, as did his volume on ‘Fortification;’ and he now compiled and published his ‘Military Bridges,’ perhaps the most generally interesting, if not the most important, of all his works. But it was not thus alone that he continued to be useful. His opinions were sought and freely given to each successive Government on every question connected with the improvement of arms, the selection of points to be fortified, the management of the navy, and the steps to be taken for putting the country in a state of defence. It is extremely interesting to know that, like the great Duke of Wellington, Sir Howard laid aside all party feeling whenever the honour or interests of the country came to be considered; and that he possessed, as he deserved, the entire confidence of Whigs not less than of Tories. His opinions as to the relative value of iron and wooden ships are well known; he was entirely opposed to the former, though he did not object to the process of casing the latter with mail; while in his ‘Naval Warfare with Steam’ he advocated a system of tactics which should bring the management of fleets very much into the same category with the management of armies in the day of battle.
