The British held out in their makeshift fort for three weeks with little water and food supplies. Many died as a result of sunstroke and lack of water. As the ground was too hard to dig graves, the British would pile the dead bodies of their killed outside the buildings, and drag and dump them inside a dried well during the night. The lack of sanitation facilities led to spread of diseases such as dysentery and cholera, further weakening the defenders. There was also a small outbreak of smallpox, although this was relatively confined.
