Main storyline pics.
The last pic of the officer straddling the bowsprit at the cap with a telescope in his hand,is actually surveying the horizon for enemy ships that may have sneaked up during the night.It was common practice when a ship was in harbor under bare poles, part of the dawn routine was to be prepared for immediate action. The flag indicates that there is a light to moderate breeze blowing and that the ship has weather cocked into the wind as it would do when at anchor.
I have never figured out what the hammock like netting behind the cap was used for ,if anyone knows please enlighten me.
The previous pic shows the marine drummer on the marines walk holding his drum after just having participated in the drumming daybreak ceremony.The fellow sitting on the head is steadying himself holding on to a rope while going about his business.
