However, the conflict became less harsh: Iancu's men concentrated on seizing local resources and supplies, opting to inflict losses only through skirmishes. The Russian intervention in June precipitated an escalation, since the Poles fighting in the Hungarian revolutionary contingents wanted to resist the Tsarist armies. Henryk Dembiński, a Polish general, negotiated for a truce between Kossuth and the Wallachian émigré revolutionaries. The latter, who were close to Iancu (especially Nicolae Bălcescu, Gheorghe Magheru, Alexandru G. Golescu, and Ion Ghica) wanted to defeat the Russian armies that had crushed their movement in September 1848.
