I first met Che one day in July or August 1955. And in one night — as he recalls in his account — he became one of the future Granma expeditionaries, although at that time the expedition possessed neither ship, nor arms, nor troops. That was how, together with Raúl, Che became one of the first two on the Granma list.
It means something like the following:
Che told a story. In his story, Che says that he became something in only one night
That something, was one of the future Granma expeditionaries
The word "account" means "story" (or maybe "book")
In this context, "to recall" means "to describe."
"Recall your birthday party in your account"
it means that you:
"Describe your birthday party in your autobiography"
