12 Nov 1987 Cunzumbia River

12 November during Operation Moduler had the SADF and UNITA soldiers resting and replenishing, with the South Africans now becoming short of mechanical spares and consumables. The SADF logistics network was hindered by the distance between South Africa and the battle sites, the inability to stockpile close to the battles due to the SADF units perpetual movement and insufficient logistics vehicles to move the supplies.

MiG bombing attacks continued on the units throughout the day but were not successful and the SADF artillery continued to target the Mianei and Chambinga crossings but they to were subject wear and tear of continuous fire and so slowing fire.
