Is this an 1857 Submarine from a War in India?

This is an exploration into photos from the 1850s searching for clues concerning the existence of a previous civilization including an 1857 Submarine.
–
1) The photos contain many buildings and anomalies that will be examined and discussed.

2) Do these photos provide evidence that a reset may have occurred just before the 1850s?

3) Bonus section examining a unique bridge in Vietnam.

The Image on the thumbnail with the 1857 Submarine is the Chattar Manzil Palace. It served as a palace for the rulers of Awadh and their wives. Later during the Indian Rebellion of 1857 the building became a stronghold of the Indian revolutionaries. Note: there is No Mention of the Submarine or power generators on the Wikipedia page. Frankly, I can’t believe that Wikipedia even included this photo! Also known as The Sepoy Mutiny.

The Chattar Manzil Palace in Lucknow, India has gone through many owners including the Nawabs of Awadh Saadat Ali Khan and Wajid Ali Shah, and the British and changes since its construction was started in the 1780s.

It served as a palace for the rulers of Awadh and their wives. Later during the Indian Rebellion of 1857 the building became a stronghold of the Indian revolutionaries.

A portion of it was destroyed by British during the war of 1857. After the war of 1857 the government had allotted the building to an American NGO which used it as a club for recreation purposes, till 1947, the Chhatar Manzil was used as the United Services Club.

Post Independence, this building was allotted to the Council of Scientific and Industrial Research which used it as Central Drug Research Institute since 1950, but now it has been vacated by CDRI. Government of Uttar Pradesh plans to set up two museums and a library at the Palace after its renovation and conservation by the State Archaeological Department.
