First offensive Soon after their arrival, the Rwandans launched an offensive alongside FADM. Simultaneous to this offensive,
Tanzania strengthened its border defenses, with the Tanzanian police carrying out operations to catch retreating rebels in Kibiti District. IS-CAP and pro-government forces clashed at Awasse; IS claimed that its forces had put up a fierce defense and killed several pro-government soldiers. It was later confirmed that the Rwandans had indeed suffered several casualties during the battle of Awasse. These successes were attributed to the Rwandans' ability to react quickly and professionally to repeated rebel ambushes along the roads. On 20 August government forces
captured Mbau, killing 11 militants. Mbau had served as the rebels' "military and spiritual headquarters"; the RDF later reported that the insurgents had even built
bunkers there. Three days later, Rwandan troops captured an insurgent base called "Ubaua" in Quissanga District; the base was possibly already abandoned, as no fighting was reported. On the same day, a FADM soldier accidentally killed a civilian in Chitunda without being punished for this, resulting in locals complaining about the military acting with impunity. On 24 August, rebels massacred ten fishermen at Mucojo, Macomia District. Two days later, the FADM stopped a boat which was possibly smuggling food supplies to rebels off Mocimboa da Praia District. A joint FADM-RDF unit captured a rebel base near Ntchinga, Muidumbe District, on 27 August. On 28 August, SAMIM troops reportedly raided an insurgent position at Muera River, capturing equipment and documents. and heavy fighting was still reported in the Messalo River valley. On 12 September, insurgents ambushed a Rwandan convoy between Mbau and Indegue, Mocímboa da Praia District, with a land mine. SAMIM troops also began to deploy in
Niassa Province; groups of insurgents were suspected of having retreated or otherwise relocated to Niassa. On 25 September, pro-government forces reportedly overran another militant base at Chitama, killing several rebels including a commander named Rajab Awadhi Ndanjile who had led the rebel forces operating in Nangade District and a founding member of the insurgency. while several reports emerged according to which pro-government militias and Mozambican security forces were abusing civilians and killing prisoners. On 1 October, FADM and insurgents battled at Miangalewa. Five days later, pro-government forces ambushed insurgents in Limala, southern Mocimboa da Praia District, killing a rebel leader known as "Muhamudu". On 20 October, rebels launched another raid into Tanzania, targeting Kilimahewa village,
Tandahimba District. They burnt a warehouse and captured several civilians, although a TPDF contingent arrived in time to rescue the hostages. For the rest of the month, insurgents attacked civilians in Macomia District. Four days later, SAMIM reportedly destroyed three rebel bases in northern Macomia District, rescuing 13 kidnapped civilians. Surviving militants fled to the north of the Messalo River. From 1 to 10 November, SADC conducted a minor offensive in eastern Muidumbe District; the operation reportedly succeeded in destroying a number of rebel bases. On 6–7 November, five rebels voluntarily surrendered to pro-government forces in Macomia and Muidumbe District. This was unusual, as the insurgents severely punish any desertion, while government forces often outright murder or torture any captured rebels; according to
Cabo Ligado researchers, the surrenders thus suggest that the supply situation of the insurgents had become very dire. Rebels also attacked Ntuleni, between Palma and Mocimboa da Praia, on 7 November, but a combined RDF-FADM force pursued, cornered and destroyed the raiding party with the help of drones. == Aftermath ==
