Loudon's bonnie woods and braes,
I maun leave them a', lassie;
Wha, can thole when Britain's faes
Would gi'e to Britons law, lassie?
Wha would shun the field o' danger?
Wha to fame would live a stranger?
Now when Freedom bids avenge her,
Wha would shun her ca', lassie?
Loudon's bonnie woods and braes,
Ha'e seen our happy bridal days,
And gentle hope shall soothe thy waes,
When I am far awa', lassie.
Hark! the swelling bugle rings,
Yielding joy to thee, laddie;
But the dolefu' bugle brings
Wacfu' thochts to me, laddie.
Lanely I may climb the mountain,
Lanely stray beside the fountain,
Still the weary moments counting,
Far frae love and thee, laddie.
Ower ths gory fields o' war,
Where Vengeance drives his crimson car,
Thou'lt maybe fa', frae me afar,
And nane to close thy e'e, laddie.
Oh, resume thy wonted smile,
Oh, suppress thy fears, lassie;
Glorious honour crowns the toil
That the soldier shares, lassie:
Heaven will shield thy faithful lover,
Till the vengeful strife is over;
Then we'll meet, nae mair to sever,
Till the day we dee, lassie:
Midst our bonnie woods and braes,
We'll spend our peaceful happy days,
As blythe's yon lichtsome lamb that plays
On Loudon's flowery lea, lassie.
