They journeyed on through Poland and through Warsaw,

Famous for mines of salt and yokes of iron:

Through Courland also, which that famous farce saw

Which gave her dukes the graceless name of "Biron."[547]'T is the same landscape which the modern Mars saw,

Who marched to Moscow, led by Fame, the Siren!

To lose by one month's frost some twenty years

Of conquest, and his guard of Grenadiers.
