How about you look at the number of days that 6 barrels of hardtack will supply 85 men according to the government in post 377 One barrel a day.. But, math aside your whole point in this exercise is to show that Lincoln shouldn't have sent ships to Sumter? So once the fort went thru all its supplies they would be totally dependent on the CSA, well wouldn't that work out just perfect for Davis.. He could pull the plug any time he wants...
No he could have sent them, and not lied about the men starving and in need of supplies, he had already chosen to retake the Fort before being sworn in, his next problem, because his cabinet and military advised against holding Sumpter, was how to manipulate opinion behind his chosen course of action.
Ok heres my work up of what your post means.
Jan 27 :
38 barrels pork:38*240*16=145920.
37 barrels flour:37*240*16=132080
13 barrels hard bread:13*240*16=48920.
March 21:
Six barrels of flour;6*240*16=23040
six barrels of hard bread6* 240*16=23040
twenty-six barrels of pork;26*240*16=99640.
25 days consumption has reduced the Jan to March levels.
Jan 27 to March 21 Table 1.
Pork 145920 less 99640 on hand,=46280 consumed in 25 days, 1851 a day. Gives 54 days supplies held.
Flour 132080 less 23040 on hand =109040 consumed in 25 days, 4361 a day. gives 5.2 days held.
hard bread 48920 less 23040 on hand, 25880 consumed in 25 days, 1035 a day. Gives 22 days held.
1st March
31 barrels pork:31*240*16=119040.
16 barrels flour:16*240*16=61440
9 barrels hard bread:9*240*16=34560
March 21:
Six barrels of flour;6*240*16=23040
six barrels of hard bread6* 240*16=23040
twenty-six barrels of pork;26*240*16=99640.
1st March to March 27 Table 2.
Pork 119040 less 99640 on hand,=19400 consumed in 20 days, 970 a day. Gives 102 days supplies held.
Flour 61440 less 23040 on hand = 38400 consumed in 20 days, 1920 a day. gives 12 days held.
hard bread 34560 less 23040 on hand, 11520 consumed in 20 days, 576 a day. Gives 20 days held.
Two things stand out, the difference in daily consumption and the effect this has on expected number of days stocks will last.
The period from 1 March to 21st March has 2 issues of the 10 day supply from Charleston so we can see the effect this has on consumption of existing stocks, ( only 1 issue of supplies can be fitted into the other time period) it reduces the need to use it by as much as 100% when compared to the average for the period Jan 27 to March 27. Why is that?, see post 359, well Anderson was only able to procure the contracter issue of supplies from the start of March and be satified with the dilivery, ( On the seventeenth of March, Anderson indicated that he was "satisfied with the existing arrangement") from Jan to that date he recieved no supplies from Charleston, which is show in the high use of supplies and lowering of stocks in the Table one. Once these supplies reached him, his consumption of existing stocks halved, table two as he was using fresh delivered supplies rather than use the longer lasting salt/hard tack.
We know he was given 184 pounds of beef, and the higher reduction of slated pork consumption can therfore be explained by the eating of the Beef, just as flour for fresh bread, rather than flour tomake bread being purchased, also fits that explanation.
