Adding up the digits in the supply number below gives 32 [1+9+3+0+5+1+6+7]. This is also the number of words in the first stanza, which is different from the other two stanzas at 26 words each.

1st of 3 stanzas is different. 1st day of march (3rd month) is when the we reached the supply listed below.

I feel like I'm missing something to tie this all together, but these are the patterns I noticed.
