Ukraine offensive underway against Russian positions

 ISW:

Ukrainian military officials announced the start of the Ukrainian counteroffensive in Kherson Oblast on August 29. Ukrainian officials reported that Ukrainian forces have broken through the first line of defenses in unspecified areas of Kherson Oblast and are seeking to take advantage of the disruption of Russian ground lines of communication caused by Ukrainian HIMARS strikes over many weeks.[1] Ukrainian officials did not confirm liberating any settlements, but some Russian milbloggers and unnamed sources speaking with Western outlets stated that Ukrainian forces liberated several settlements west and northwest of Kherson City, near the Ukrainian bridgehead over the Inhulets River, and south of the Kherson-Dnipropetrovsk Oblast border.[2] The Russian Defense Ministry (MoD), Russian proxies, and some Russian milbloggers denounced the Ukrainian announcement of the counteroffensive as “propaganda.”[3]

Many Russian milbloggers nevertheless reported a wide variety of Ukrainian attacks along the entire line of contact, and the information space will likely become confused for a time due to panic among Russian sources.[4] Russian outlets have also vaguely mentioned evacuations of civilians from Kherson Oblast, but then noted that occupation authorities in Kherson Oblast are calling on residents to seek shelter rather than flee.[5] ISW will report on the Ukrainian counteroffensive in a new section below.

The Russian media is claiming the offensive failed.

 Ukraine’s counter-offensive attempt has failed – Russia

Kiev’s troops suffered great losses in a failed attack ordered by president Zelensky towards Kherson, Moscow says

RT is quoting the Russian defense ministry saying several armored vehicles were destroyed and claiming 560 Ukraine casualties.  It is not clear how they could count them in the middle of a battle unless there was a retreat.  But the RT story appears inconsistent with what some Russian milbloggers are reporting.

ISW further reports:

Ukrainian military officials announced that Ukrainian forces began a counteroffensive operation in Kherson Oblast on August 29 after severely disrupting Russian ground lines of communication (GLOCs) for weeks. Southern Operational Command Spokesperson Nataliya Gumenyuk stated that Ukrainian forces “began counteroffensive actions in many directions” and have broken through the first line of defense in an unspecified area.[11] The Ukrainian operational group “Kakhovka” stated that Ukrainian forces have cut Russian GLOCs across the Dnipro River in Kherson Oblast and called the situation a “brilliant chance to return [Ukrainian] territories.”[12] The “Kakhovka” group also reported that the Donetsk People’s Republic (DNR) 109th Regiment and Russian airborne troops have left their positions in an unspecified area of Kherson Oblast, and Ukrainian wires claimed that these elements withdrew from their positions around Kherson City.[13] The DNR 109th Regiment had previously published an appeal to Russian President Vladimir Putin in late June identifying itself as a forcibly mobilized unit, complaining that it had not been rotated away from the front line for rest, and decrying poor conditions on the frontlines.[14] Ukrainian military officials also released a DNR document dated July 24 that ordered the redeployment of the 109th, 113th, and 125th DNR regiments to Arkhanhelske, Vysokopillya, Zolota Balka, and Davydiv Brid in northwestern Kherson Oblast.[15] “Kakhovka” also shared footage reportedly of a Russian serviceman seeking shelter on the ground amidst heavy artillery shelling while saying that Ukrainian forces have broken the first line of defense on August 29.[16] Ukrainian officials did not discuss the directionality of Ukrainian counteroffensives.
