Who was the puritan captain in longfellow's poem who was to shy to propose to his girlfriend?

In Henry Wadsworth Longfellow's poem "The Courtship of Miles Standish," the Puritan captain is Miles Standish himself. He is portrayed as a brave and valiant soldier, yet he is too shy and hesitant to propose to his love interest, Priscilla Mullins. Instead, he asks his friend John Alden to speak to her on his behalf, which ultimately leads to a twist in their romantic dynamics.
