Descripción:

It should be noted that, according to Kubanin, Chaldon
arrived in the Makhnoshchina as part of Chernyak's group, so he
may have been a Makhnovist kontrrazvednik. Kostyukin took part
in the operations of the Special Strike Force in Kharkov, Yekater-
inoslav, and Odessa, At an inquiry into the assassination attempt,
it was clarified that the plan had been developed personally by the
head of the All-Ukrainian Cheka Mantsev, along with Martinov and
Glushchenko. Kostyukin and Glushchenko were also supposed to
recruit Zinkovsky. On June 21 both terrorists were shot.
