A Rebus

I.

A bird delicious to the taste,
On which an army once did feast,
Sent by an hand unseen;
A creature of the horned race,
Which Britain's royal standards grace;
A gem of vivid green;

II.

A town of gaiety and sport,
Where beaux and beauteous nymphs resort,
And gallantry doth reign;
A Dardan hero fam'd of old
For youth and beauty, as we're told,
And by a monarch slain;

III.

A peer of popular applause,
Who doth our violated laws,
And grievances proclaim.
Th' initials show a vanquish'd town,
That adds fresh glory and renown
To old Britannia's fame.
