‘At that time’

William May in later years.

Admiral of the Fleet Sir William H. May, whose career in the Royal Navy spanned nearly fifty years, wrote in his privately-printed memoirs:

I was promoted to Lieutenant in August, 1871. At that time lieutenants just promoted were generally three or four years on half pay before getting a ship, and the half pay was 4s. a day at the average age of 22. Luckily, Lord Clanwilliam, who was just about to turn over the command of the Hercules to Captain William Dowell, recommended me to fill a vacancy there was for lieutenant, and I was duly appointed after having been only four months on half pay.

May had actually been promoted on 7 September 1871, not in August. He spent two days short of seven months on half pay between appointments upon promotion, not four. And then we move onto his claim regarding the half pay of other Lieutenants. In 1871 forty were promoted. Three did not serve in that rank and retired. 17 carried on in their new rank straight away. Of the others, no one was kept on half pay longer than 14 months—nowhere near May’s ‘three or four years’.

I’ve pointed out before (on this site, and elsewhere) the perils of relying on memoirs, but this is a particularly inaccurate passage by anybody’s standards.
