9 in the evening
Parade assembly is at 5.30 at this time of the year , with retreat and evening gun-fire at 6.10 . Then comes mess call to supper . With that ends , usually , the working day of the enlisted man . Tattoo sounds at 9 in the evening , with call to quarters at 10.45 , and taps , or lights out , at 11 p. m. Except when on guard or special duty you 're not likely to have to be with your men much after retreat . '' `` Oh , I should hope not , '' exclaimed Algy Ferrers fervently . `` By supper time I can see myself a nervous wreck . '' `` Oh , you 'll get used to it , '' laughed Prescott .
