Ajay Singh Rawat writes that the year of invasion mentioned by these writers is not correct, and the animosity between Fateh Shah and Raja of Sirmur is the prelude to the Battle of Bhangani (1688).

Guru Gobind Singh had sent jewellery worth one lakh rupees to Fateh Shah's daughter at the time of marriage ceremony.

[3] Later, the combined forces of Bhim Chand and Fateh Shah launched an attack on Guru Gobind Singh's camp.

Guru Gobind Singh was already prepared for a battle, and the two forces met at Bhangani, located about six miles from Paonta, on 18 September 1688.

Dr. Fauja Singh believes that the Battle of Bhangani should not be connected with the story of Fateh Shah's refusal of the wedding presents sent by the Guru.

[3] The author of Bichitra Natak doesn't mention the name of Raja Bhim Chand, and states that Fateh Shah fought with him for no obvious reasons.

[3] According to Ajay Singh Rawat, one of the possible grievances of Fateh Shah could have been the presence of Guru's armed camp near his territory; Paonta was a strategic location on the only convenient route connecting Nahan (capital of Sirmur) and Garhwal.

[8] Fateh Shah appears to have returned very soon to Garhwal; in 1710, he mobilized his troops in Badhan.After this he conquered the areas of katyur valley (modern day Baijnath) and donated a village named Garsaar to the Badrinath temple.
