first option - to to inform the troops of their obligations

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."
