Final answer:
The slaughter of Sikh children occurred during the partition of India in 1947, which resulted in widespread violence and casualties.
Step-by-step explanation:
The slaughter of Sikh children mentioned in the question is likely referring to the violence and casualties suffered by Sikh children during the partition of India in 1947.
The partition, also known as the partition of India and Pakistan, occurred when British India was divided into two separate nations, India and Pakistan.
