In Henry V, how does the Prologue of Act III deal with the issue of nationalism?

A key function of the Chorus in this excellent play is to
"fill in the blanks" as it were of what the staging is unable to achieve, and to ask the
audience to use their imagination, helped by his words, to "see" what cannot be shown on
stage. Thus it is that the Chorus pleads with the audience to "eke out our performance
with your mind" and to "Work, work your thoughts." Through the description of the Chorus
in this speech and the power of our own imagination, we are encouraged to see the navy
leave England and sail to France, and we are taken to a
siege.

It is key to realise that, when it comes to the
theme of nationalism, the Chorus in this play presents one perspective or voice. The
bombastic nature of the Chorus would lead us to believe that everyone in England is
swept up in some kind of nationalistic frenzy, as the following lines
suggest:

Grapple your minds to sternage of this
nave,

And leave your England, as dead midnight
still,

Guarded with grandsires, babies and old
women,

Either past or not arrived to pith and
puissance;

For who is he, whose chin is but
enrich'd

With one appearing hair, that will not
follow

These cull'd and choice-drawn cavaliers to
France?

If we were to listen
to the Chorus alone, we would think that all men of age were taken by Henry to fight in
France, leaving England only populated by women, infants and old men. The rhetorical
question infers that every man would, for honour's sake, be willing to fight for England
and go to France. However, before we get swept away, let us remember that Pistol and his
cronies are going to France to fight for the soul purpose of making profit. Thus we can
see that the nationalistic spirit of the Chorus is undercut by other, dissenting voices
in the play.
