In later works, Russian historians such as Mikhail Meltyukhov and Oleg Vishlyov dismiss the parades in other cities as "a myth", pointing to the fact that virtually no evidence has been found to confirm that those parades actually took place.[15] In Lwow, Vishlyov states, it was impossible to organize a joint parade, as the Soviet troops were ordered to move to a distance of 20 km (12 mi) from the Germans after an accidental exchange of fire between the two sides, and no German units were present there at the time when the city capitulated to the Soviets. Vishlyov also disputes that the events in Brest were a military parade and writes that what is often mistakenly regarded as a parade was in fact a "ceremonial departure of German forces under the supervision of Soviet representatives".
