In the southern region of Ukraine, where the Kakhovka Dam once created a vast reservoir along the Dnipro River, fierce and unconventional warfare is unfolding amid dense reeds, scrub, and willow thickets. Since the dam’s destruction three years ago drained the reservoir, the former flood plain has transformed into a challenging battleground that limits the effectiveness of modern technology like drones, forcing soldiers on both sides into close-quarters combat.
Russian forces, including elements of the elite 40th Combined Arms Army, have concentrated their efforts to penetrate this difficult terrain in an attempt to advance toward the industrial city of Zaporizhzhia, located on the former reservoir’s northern shore. With a prewar population of approximately 750,000, control of Zaporizhzhia would hold significant strategic value, including influence over Ukraine’s energy infrastructure and broader regional security.
Ukrainian military intelligence units such as the volunteer-formed Bratstvo battalion have been defending the area, engaging Russian troops in relentless battles that differ markedly from open-field combat or urban warfare seen elsewhere in the conflict. Soldiers describe the battleground as a suffocating, mosquito-infested jungle where visibility is limited, and even friendly forces can be just steps away without clear sight.
Commanders on both sides note the intense, close-range nature of fighting here, with infantry and snipers playing a decisive role due to the terrain’s unsuitability for tanks, artillery, and many drone operations. Ukrainian battalion leaders liken the Russian logistical efforts in the swampy basin to the Ho Chi Minh Trail from the Vietnam War, highlighting the challenges of supply and maneuver under the dense vegetation.
Encounters between Ukrainian and Russian troops often take the form of night movements, ambushes, and reconnaissance missions. In one instance, a Ukrainian reconnaissance squad killed four Russian soldiers and captured two others on a rocky outcrop that once emerged from the reservoir’s waters. Such skirmishes yield important intelligence and disrupt opposing forces' deployments.
While some Russian soldiers are described by Ukrainian commanders as skilled fighters, others are seen as inexperienced, reflecting a decline in troop quality reportedly linked to recent Russian conscription efforts. The increased number of Russian surrenders in the area has been attributed, in part, to new information spreading among Russian ranks about the relatively humane treatment of prisoners by Ukrainian forces, contrary to earlier Russian propaganda.
Ukrainian commanders expressed concern about the human cost of the fighting, questioning the rationale for the sustained loss of life on both sides. Despite the brutal and grueling conditions, Ukrainian forces have largely repelled Russian advances in recent months, though they remain vigilant ahead of anticipated new Russian offensives amid ongoing mobilization efforts by Moscow.
The battles in the former reservoir basin continue to shape the broader contest for control in southern Ukraine, with both armies deeply entrenched in this unforgiving environment as they vie for strategic advantage in the long-running conflict.
