Explanation:

• Lachit Borphukan was an army general from Assam, India. He is remembered for his extraordinary victory against the Mughal army of Aurangzeb headed by Ram Singh in the Battle of Saraighat (fought in 1671 between the Mughals and the Ahom Kingdom on the Brahmaputra river at Saraighat, now in Guwahati).
• In this battle the weaker, the Ahom Army defeated the Mughal Army by brilliant uses of the terrain, clever diplomatic negotiations to buy time, guerrilla tactics, psychological warfare, military intelligence and by exploiting the sole weakness of the Mughal forces—its navy.
• His father, Momai Tamuli Borbarua was the ‘Governor’ of the kingdom and also ‘Commander-in-Chief’ of Ahom army under King Pratap Singha during his reign starting from 1603 to 1639.
• Lachit received military training from an early age and joined the Ahom King Jayadhvaj Singha (1648-1663) as a scarf-bearer. The post ‘scarf-bearer’ or ‘Soladhara Barua’ is considered as a part of the incumbent king’s personal staff.
• In August 1667, Chakradhvaj Singha appointed Lachit Borphukan as the Commander-in-Chief of Ahom kingdom.

Hence both statements are correct.
