Analysis of Epitaph on a Jacobite

To my true king I offered free from stain
Courage and faith; vain faith, and courage vain.
For him, I threw lands, honours, wealth, away.
And one dear hope, that was more prized than they.
For him I languished in a foreign clime,
Grey-haired with sorrow in my manhood's prime;
Heard on Lavernia Scargill's whispering trees,
And pined by Arno for my lovelier Tees;
Beheld each night my home in fevered sleep,
Each morning started from the dream to weep;
Till God who saw me tried too sorely, gave
The resting place I asked, an early grave.
Oh thou, whom chance leads to this nameless stone,
From that proud country which was once mine own,
By those white cliffs I never more must see,
By that dear language which I spake like thee,
Forget all feuds, and shed one English tear
O'er English dust. A broken heart lies here.
