There’s a military connection here I can’t quite piece together:
During WWII, US infantry in the UK were called “Dough boys”
“the far side of the swim” - across the Atlantic?
“a waiting troop”
It’s as if it’s addressed to a young woman who has travelled from the UK to the USA to live in a military base or town.
Maybe someone else can figure out more…
