The East Sudan War is an ongoing conflict in south-east Sudan over control of the resource rich area of the Upper Nile region of South Sudan. Tension between the two countries reached a massive high when South Sudanese militia occupied the area to protect it and East Sudan tripled the size of their border guard force in a month. Despite the fact that their guard forces were larger than the entire SPLA, East Sudan held off invading the country for fear of reprisal from other Sudanese successor states. This fear was removed in late November when several of the successors to Sudan signed a treaty declaring that they wouldn't intervene if South Sudan was invaded.
East Sudan spent most of December mobilizing its forces towards the border with South Sudan and reinforcing its border with Ethiopia and Eritrea. The date set for the attack was December the 26th as it was assumed that the SPLA troops wouldn't be prepared for an invasion on one of their national holidays. The Eastern Sudanese plan was a great success, catching the entire SPLA off guard and preventing the CAMC from responding quickly. In the first week of the war the Eastern Sudanese Army (ESA) had captured most of the Upper Nile region and the CAMC high command was still paralyzed. By late January the CAMC had finally organized its forces and Ethiopian army forces as well as air forces from Ethiopia and Eritrea moved into South Sudan, with the help of SPLA guerrillas the CAMC forces were able to eject ESA troops from South Sudan.
However, ESA forces still outnumber the combined CAMC task force although the CAMC air forces have a numerical and technological advantage. In March 2010 Eritrean forces launched a naval assault with 5000 naval Infantry and occupied north-east Sudan, SPLA regular units have also occupied the region to ensure it stays in CAMC hands.
Despite the fact that Eritrea and South Sudan were both committing their entire military to the conflict in East Sudan the majority of the Ethiopian army was still in Somalia fighting the ICU. However, when Ethiopia signed a peace treaty with the Republic of Somalia at the 2010 Socialist International Conference a further 20,000 Ethiopian army forces became available and in the following two weeks the majority of those troops were transferred into South Sudan.
Towards the beginning of August 2010 the CAMC's civilian planners drew up plans for the annexation and occupation of East Sudan while the military under Ligan Lopez drew up a plan that would cripple the East Sudanese military and allow the Eritrean naval infantry to occupy the capital alongside the Ethiopian Elite Air Corps. On August the 6th Operation Peregrine Falcon was launched and the entire CAMC's Air Force was launched against military bases in East Sudan crippling the ESA. The majority of East Sudan's tank forces were completely destroyed while the East Sudanese Air Force was severely damaged during the attacks.
Soon the CAMC's land forces moved into East Sudan capturing the capital and killing President Gaafar Nimeiry. With the capture of the capital the East Sudanese forces surrendered to the CAMC and the country was annexed into South Sudan. This was greeted with great relief by the citizens of East Sudan and the South Sudanese government has taken over most of East Sudan's government institutions. To ensure that there is no danger to the new regime, Ethiopian military forces will remain in the country until the official handover to South Sudan on August the 30th.
As the states of the Confederation of African Marxist Countries are regional partners of the CSTO, supplies from Siberia and the Caribbean have been coming into the CAMC from the beginning of the conflict.
