The offensive culminated in the Battle of Uvira in which rebels attempted to capture the major city, but were eventually pushed out by state security forces.[7] The offensive continued after the battle, but then ended as a counter offensive by the FARDC began in December.[1]
The CNPSC coalition was brokered by William Yakutumba, a prominent Mai-Mai commander involved in armed rebellion since the 1990s.[8] It unified around 12 Mai-Mai groups into a coalition, aimed at removing the government of Joseph Kabila, who had delayed scheduled elections in late 2016. The idea of the coalition had been around since about 2013, but only became in existence after Kabila's electoral delay. Several armed groups came to be prominent in the group, notably Yakutumba's PARC-FAAL, the Mai-Mai Malaika, and the Uvira hills-based Mai-Mai groups of René Itongwa, Réunion Warusasa, and several others.[9]

General Philemon Yav was selected to become the commander of the Sukola II operation, and would lead military operations against the CNPSC.[2] This date is generally accepted as when the offensive ended, as a large-scale FARDC counter-offensive launched by Yav would begin in the following weeks.
Aftermath
Following Philemon Yav's appointment as overall commander of Sukola II, the FARDC began a major offensive against the CNPSC rebels which was intended to destroy the group.[1] Heavy losses were inflicted against the group, mainly against Yakutumba's Mai-Mai militia, and the group was falsely labeled as "annihilated" by the army.[26] In late 2018, another CNPSC offensive would be launched.
Towards the end of the offensive, FARDC forces targeted Bembe civilians, who they believed to be CNPSC rebels.[2] Arbitrary arrests of Bembes, specifically young adults, were carried out in Baraka and Uvira. This harassment led to a recruitment spike for the coalition.[2]
