In conventional terms, the FAPLA brigades theoretically possessed more than enough strength and firepower to dislodge UNITA and the SADF from the Lomba River. But they were inadequately trained or experienced to counter the South African blocking force, which was composed of units selected for their experience in mobile bush warfare, and were outmanoeuvred in the thick foliage cover. The Lomba's swampy environment also hampered coordinated actions and allowed the SADF to isolate and route each brigade in piecemeal engagements. Between September and October 1987 FAPLA suffered almost 2,000 casualties during several failed river crossings. With much of its bridging equipment destroyed, FAPLA abandoned the offensive and ordered its remaining brigades back to Cuito Cuanavale. The Soviet military mission had suffered 1 seriously wounded. The SADF had suffered 17 dead and 41 wounded, as well as the loss of 5 armoured vehicles.
