[4] Henry IV obliged to send 3,000 lansquenets, who should gain their payment by ravaging and plundering the free peasants of Wursten, once successfully subjected.

[3][5] By 20 November 1499 Magnus hired the so-called Great or Black Guard of ruthless and violent Dutch and East Frisian mercenaries, commanded by Thomas Slentz, prior operating in Oldenburg.

[9] Finally on Christmas Eve arriving downstream the Weser in Lehe the Black Guard tried to invade Wursten, however, the free peasants there repelled their attack near Weddewarden on 26 December.

[12] In return Rode had to offer appointing Henry's 12-year-old son Christopher as his coadjutor, a position usually (as coadiutor cum iure succedendi), and in this case indeed, entailing the succession to the respective see.

[12] This exactly accomplished Henry's own expansionist ambitions, so he changed sides, dropped the alliance with Magnus and John V in order to militarily support the prince-archbishopric.

[9] Hadeln was restored to Magnus, while the Wursteners rendered homage to Rode on 18 August, who in return had confirmed their autonomy, thus in fact little had changed as compared with the status quo ante.

The electoral swords indicated the office as Imperial Arch-Marshal (Erzmarschall, Archimarescallus), pertaining to the privilege as prince-elector, besides the much more important right to elect the new emperor after the decease of the former.

Charles V, Holy Roman Emperor, enfeoffed Magnus with the Duchy of Saxony, Angria and Westphalia (so its official name, but colloquially Saxe-Lauenburg) and the pertaining regalia at the imperial diet in Augsburg on 12 November 1530.

The imperial writ of feoffment emphasises, that Magnus had requested to be also enfeoffed with the Saxon electoral privilege, however, further explaining that this could not happen at that time "due to moving reasons".
