Final answer:
The Wada Ghalughaaraa references to the major massacre during the Sikh holocaust by Mughal forces without exact figures of casualties available.
Step-by-step explanation:
The Wada Ghalughaaraa refers to a major massacre during the Sikh holocaust that took place when Mughal forces clashed with Sikh warriors. While historical records do not provide an exact figure for the number of Sikhs massacred out of the 30,000 present, it is largely accepted that a great number suffered at the hands of the Mughal army.
This tragic event is embedded in the history of Sikh-Mughal relations and represents the severe persecution that the Sikhs faced during this period.
Given the context and the figure of 30,000 Sikhs mentioned in the question, it appears that this particular inquiry could be a mix-up with another historical incident, as the Wada Ghalughaaraa traditionally refers to mass killings that took place in the 18th century.
However, due to a lack of specific information regarding the numbers in this particular scenario, an accurate count of the casualties cannot be provided.
