JAS’s Lake Chad Resilience
The Bara Tolorom Attack and Boko Haram’s Persistent Insurgent Adaptation
In mid-May 2026, Jamāʿat Ahl as-Sunna li-daʿwa wa l-Jihād (JAS), commonly known as Boko Haram, released a video showing an assault conducted with armed boats against a Chadian military position in the Bara Tolorom area of Lake Chad. The footage, distributed through jihadist channels, reportedly documented a raid targeting Chadian forces operating in the borderland environment of the Lake Chad Basin.
The operation is analytically significant because it illustrates a persistent but often underestimated reality within the Lake Chad insurgency ecosystem: despite years of military pressure, fragmentation, territorial losses, and sustained competition with Islamic State West Africa Province, JAS retains the capacity to conduct cross-border insurgent activity, project violence within littoral Lake Chad environments, and sustain operational relevance through asymmetric adaptation.
The Bara Tolorom attack also highlights how JAS has evolved since the death of former leader Abubakar Shekau in 2021. Rather than functioning as a territorially expansive proto-state insurgency, the group increasingly operates through decentralised armed cells embedded in weakly governed rural and borderland environments, prioritising survivability, coercive local influence, and opportunistic attacks against regional security actors.

JAS After Shekau: Fragmentation Without Collapse
Since the internal rupture with ISWAP and the death of Shekau during clashes with rival jihadists in Sambisa Forest in 2021, regional security assessments have frequently portrayed JAS as a collapsing insurgent structure. While the organisation undeniably suffered severe organisational degradation, the movement did not disappear. Instead, it adapted into a fragmented but resilient insurgent ecosystem.
Current JAS operational activity indicates that the organisation no longer prioritises large-scale territorial governance, as it did during the 2013–2015 period, when Boko Haram temporarily controlled extensive territory across northeastern Nigeria. Instead, residual factions concentrated around Sambisa Forest and peripheral Lake Chad environments now emphasise survival-oriented insurgency, mobile warfare, coercive governance, and asymmetric violence against local communities and security forces.
The continued operational activity of residual factions associated with commanders such as Bakura Modu, commonly known as Bakura Doro, further suggests that elements of the post-Shekau JAS ecosystem have retained sufficient cohesion to sustain insurgent activity despite years of organisational fragmentation, leadership attrition, and sustained military pressure. While the movement no longer operates under a unified command structure, the persistence of influential field commanders appears to have contributed to the survival of localised insurgent networks across portions of the Lake Chad Basin.
The Bara Tolorom attack reflects this adaptation model. The use of armed boats demonstrates that JAS retains operational familiarity with the geography and tactical realities of the Lake Chad Basin, an environment characterised by islands, marshlands, shallow waterways, informal fishing routes, and porous borders difficult for conventional military forces to control fully. Similar mobility patterns have historically enabled jihadist factions to evade counterterrorism pressure, sustain smuggling routes, and relocate fighters between Nigeria, Chad, Niger, and Cameroon.
Importantly, JAS continues to benefit from structural conditions that remain largely unresolved across the region. Chronic underdevelopment, displacement crises, weak state penetration, illicit trade economies, and fragmented local governance continue to provide permissive operating conditions for insurgent survival.
The insurgency’s persistence therefore cannot be understood exclusively through military metrics such as territorial control or leadership decapitation. JAS increasingly behaves like a resilient low-intensity insurgent network embedded within fragile borderland systems rather than a conventional territorial insurgency.
The Return of Lake Chad Manoeuvre Capability
Beyond the immediate tactical outcome, the Bara Tolorom attack highlights an increasingly important but often overlooked aspect of the Lake Chad insurgency: the continued viability of waterborne manoeuvre operations. The use of armed boats demonstrates that JAS retains operational familiarity with the lake environment and remains capable of exploiting waterways for mobility, concealment, and force projection. While insurgent use of boats in the basin is not a new phenomenon, the operation serves as a reminder that the lake continues to function as a permissive operational space despite years of regional counterinsurgency efforts.
