[3] In July 1999 SSDN Commander Tito Biel, who had been given ammunition by the SPLA, launched an attack on Paulino Matiep's forces and pushed them back almost to their headquarters in Mankien.

[10] After the civil war, a team found that 4% of people around Mankien were blind, and almost 8% more had poor vision, mainly due to untreated diseases such as Trachoma.

[13] After further fighting in May 2011, when Peter's forces attacked Mankien from his home village of Ruadnyibol, the Mayom county commissioner said that about 7,800 huts had been burned.

[14] While reporting on mine clearance operations around Mankien, the project manager for Norwegian People's Aid said "Unity State remains one of the most contaminated states in South Sudan, with a high number of Dangerous Areas, several minefields and a high number of abandoned ordnance contaminating huge areas of land".
