The Yankees did invade us,
To kill and to destroy,
And to distress our country,
Our peace for to annoy,
Our countrymen were filled
With sorrow, grief and woe,
To think that they should fall
By such an unnatural foe.

John Watson as a British officer stationed at York (later Toronto) after the Americans burned and sacked the city during the War of 1812.
