Historically he did not make Poland loyal almost at all. Poland's loyalty was always questionable hence all the revolts, Cursed Soldiers, and USSR tendency to smash down on Poland.

My first post was the NKVD and USSR officers being kicked out because it was around this time things started to get really bad for Poland. If the NKVD and Soviet officers were not to get removed then thousands more Poles would die in the next 2 years causing more revolts in 2-6 years with thousands more dead. Reconciliation and free Poland is my guy's goal since that will save Poland he believes.
