Our first full general was U. S. Grant and our first full admiral, David D. Porter; both won their rank in the Civil War. In that war there was a large increase in the Navy and more naval ranks were established. In 1862 ensign was provided in the Navy to correspond to second lieutenant; and the term lieutenant commanding became lieutenant commander. An ensign wore one stripe as now; an additional stripe was added for each rank till the rear admiral had eight. Since 1869 the senior officers have worn the same stripes as now prescribed. In 1883 the rank "master" was changed to lieutenant, junior grade. The rank of commodore, which had been abolished, was temporarily revived during World War II. The rank of passed-midshipman was abolished about 1910; thereafter graduates of the Naval Academy were commissioned ensign. The rank of ensign had previously been attained by passed-midshipmen after 2 years at sea and a successful examination at the end of that cruise. The only permanent change in recent years was the addition of aviation cadet to both the Air Force and Navy listings. The warrant rank of flight officer in the Air Force, which was created during the war, has now been abandoned, all the flight officers then holding warrants either being commissioned second lieutenants or separated. The naval rank of commodore was likewise dropped, and brigadier generals of the Army and Air Force now rank with admirals of the lower half. The following are the present corresponding ranks in the Armed Services:
