President Zelensky's adviser said Russia changed tactics to strengthen the Donetsk defense, and at the same time dispatched a large amount of troops to the three provinces of southern Ukraine.

Oleksiy Arestovych, a senior adviser of Ukrainian President Volodymyr Zelensky, said on July 27 that Russia seemed to be moving from attack to strategic defense, using tactical raids to weaken the ability to attack the attack.

Oleksiy Danilov, Secretary of the Ukrainian National Defense and Security Council, said Russia is focusing the maximum number of soldiers to the southern province of Kherson but does not give details.

This will put us in a position that is difficult to regain the entire territory and have to call for negotiations, he said, and confirmed that the Russian forces had controlled the second largest Vuhlehirk power plant Ukraine.

Vuhlehirska is the second largest power plant Ukraine, located about 50 km from the Eastern Province of the East Province.

British intelligence previously said that the Russian forces are giving priority to controlling the important infrastructure of Ukraine, including power plants, and at the same time built the attack on the southern cities's pincers in the two important cities in the province.

The Ukrainian battlefield situation after more than 5 months of fighting.

In April, Russia withdrew from northern Ukraine surrounding Kiev capital to focus on the Donbass region in the East, including two provinces of Lugansk and Donetsk.

Russian Foreign Minister Sergey Lavrov on July 20 announced its military goal in Ukraine no longer focused on Donbass in the East, but expanded to the South and other regions.

Ukraine plans to open a counterattack campaign to recapture Kherson, but they need more weapons and human resources than what is available.

The British Ministry of Defense said that Russian forces gained a tactical advantage when approaching the Vuhlehirska power plant in Donbass, forcing many Ukrainian units to withdraw.
