parties, now in exile and opposition and gathered together under the
umbrella of the National Democratic Alliance (NDA).
But the civil wars in Ethiopia were also intensifying at this time.
Khartoum (with US support) backed the Eritrean People’s Liberation
Front, Tigray People’s Liberation Front, Oromo Liberation Front and
other anti-Mengistu forces, while the SPLA became increasingly involved
in giving armed support to its patron, much to its cost, both militarily
and politically.
The military position was delicately poised by the beginning of 1991.
The SPLA looked as if it was about to take control of most of the south,
including Juba. But the fall of Mengistu in May deprived the SPLA of
its bases, its supplies and its support and left it vulnerable to a flanking
attack through Ethiopia by the Sudanese army, who had backed the
winning side.
The SPLA’s policy of suppressing political dissent within the movement
also had the opposite effect to that intended, and weakened its cohesion.
A challenge to Garang’s leadership was launched by two commanders in
Nasir, now left vulnerable by the collapse of their former Ethiopian ally.
In August 1991 Riek Machar and Lam Akol declared over the BBC World
Service that Garang was overthrown and that the movement would
henceforth fight for the total independence of the south.
Garang, based some hundreds of miles away in Torit, was far from
overthrown, but the split was serious. The Nasir faction had the surrep-
titious support of Khartoum, who arranged an apparent transfer of
allegiance of their remaining Anyanya II militias. Over the next year
some very prominent SPLA commanders who had also fallen out with
Garang went over to the Nasir side. Fighting broke out in areas the SPLA
had previously secured, and Garang was spooked into desperate actions
of his own: he attempted to open a second front in Darfur, which failed,
and he launched a premature attack on Juba, which came near to success,
but also failed. Between 1993 and 1995 Khartoum was able to press the
SPLA severely in Eastern Equatoria and the area between Juba and theThe Sudan Handbook, edited by John Ryle, Justin Willis, Suliman Baldo and Jok Madut Jok. © 2011 Rift Valley Institute and contributors Uganda border.
