Black nationalist leader Winnie Mandela, defying an order to return to the remote township to which she has been banished, headed for Cape Town yesterday to try to visit her jailed husband, Nelson, leader of the banned African National Congress.

Winnie Mandela stayed in Soweto, Johannesburg's black satellite city, a day beyond the deadline for her return to Brandfort, 235 miles to the south, Reuter reported. The family has a home in Soweto.

Since August, when her Brandfort home was firebombed, she has divided her time between Soweto and Cape Town, where her husband is serving a life sentence. She was banished to Brandfort in 1977.

Nelson Mandela is now in a hospital recovering from prostate gland surgery.

In another development, troops moved into Soweto's Baragwanath Hospital to replace fired auxiliary workers. The workers' protests over pay and conditions led to violence Wednesday, when police arrested 718 employes on charges of attending an illegal gathering.

Violence erupted overnight, adding to the death toll of more than 800 in the past year.

Police said a 63-year-old man was dragged from his home by youths, stabbed to death and his body set afire at Hoffmeir in eastern Cape Province. In the northern Cape, police said a man was shot to death when a policeman working for the local black affairs board fired on a group of people who reportedly were stoning him.
