In Shakespeare's "Henry V," which character declares, "If we are marked to die, we are enough / To do our country loss" (Act IV, Scene iii, lines 20-21)?

Explanation

The quote is spoken by King Henry V in Act IV, Scene iii, expressing his resolve and acceptance of fate before battle. Falstaff does not appear in this play, Nim is a minor character, and Princess Catherine is unrelated to this speech.
