Step-by-step explanation:
The phrase 'the sullen dignity of their defeat' in line 16 of the poem reinforces the statement 'their anger is still alive' by conveying a sense of resignation and acceptance rather than anger.
The word choice of 'sullen' suggests a subdued or gloomy demeanor, which implies that the Zulu people have not let go of their anger but are instead dealing with it in a dignified and controlled manner.
This idea is further supported by the concept of defeat, which implies that they have experienced loss and disappointment, but their anger still persists.
