Explanation:

Before battles, it was common for the troops to be addressed by those in command to reassure their presence and loyalty and motivate soldiers for the fight.  In her address to the troops in Tilbury, Queen Elizabeth meant to  establish her place as their dutiful commander. At a time when women were not seen as men's equals, she assured them that her willingness to die for them and the honor of their country made her a commander worthy of their trust and respect as well as made up for the fact that she was a woman. As per her own words,

"and therefore I am come amongst you, as you see, at this time, not for my recreation and disport, but being resolved, in the midst and heat of the battle, to live and die amongst you all; to lay down for my God, and for my kingdom, and my people, my honour and my blood, even in the dust."

boccaccio employs the voice of his narrator dioneo to represent his ideas on the tension between masculinity and femininity.  while dioneo excites the members of the brigata and recognizes women for their unique skills and independent ideas, he concludes the decameron with a story reminiscent of the society from which these young aristocrats escaped, revealing misogynistic overtones.  dioneo boccaccio is able to explore the gender disparity which is inherent in 14th century florentine society.
