Jackson and his younger brother Robert got captured by British. Jackson left with a permanent scar when a British Officer gashed Jackson's right hand and slashed his face with a sword. The British Officer did this, because Jackson refused to polish the Redcoat's boots. Robert got smallpox and was not recovering. Jackson's mother arranged release and soon after, Robert died. Not long after Robert's death, his mother died of cholera.
She caught it while nursing sick and injured soldiers back to health.
