Answer: To get the refugees to leave
Step-by-step explanation:
In the book, A Long Walk to Water, Salva Dut was a young refugee of the Sudanese Civil war who had lost his family and moved from one refugee camp to another until he ended up in Ethiopia.
In 1991, the Ethiopian government decided to send the refugees back home and sent their soldiers to enforce this. When the soldiers arrived at the refugee camp, they started firing bullets and shouting to get the people to cross the Gilo river back into Sudan.
