The war with the House of Ascania…

The war with the House of Ascania is not limited to the border areas of Greater Poland.

By 1272, Duke Boleslaw V had entered in an alliance with Mestwin II, Duke of Pomerania-Gdańsk; one year later (in 1273), he had renewed his homage to Brandenburg and promised his help to the Margraviate against all his enemies, except the Duke of Greater Poland.

In the same year was launched another expedition against Brandenburg.

Although the nominal leadership of the troops had been given by Bolesłlaw to his young nephew Przemysl II, the expedition was actually headed by experimented commanders such as the voivode of Poznań, Przedpelk Lodzia, and the castellan of Kalisz Janek.

They successfully reconquered both Drezdenko and Strzelce.

The last campaign against Brandenburg during Boleslaw's lifetime occurs in the summer of 1278, when the Greater Poland troops advance as far as Myślibórz and eventually recover Santok.
