How to unarchive gmail messages that disappeared from my inbox?

[arclion]

On my mobile phone, I swiped on a very crucial thread, and now all the conversation is gone out of my primary inbox. I knew it was archived, but I do not see a folder that is particularly named archive in the sidebar. I've tried searching for the sender's name, but I want to know how to unarchive gmail so the thread actually stays back in my main inbox permanently. How can this be done in bulk in case I have already archived several emails. I am afraid that I will not meet a deadline due to the inability to see the thread anymore. It would be great to get an indication where all these emails disappear to.

To reread messages that have been deleted out of your Gmail inbox:
Go to All Mail in the left sidebar of the open Gmail.
Find the email you want.
Open it and press Move to Inbox (or the inbox icon).
Hint: Search bar can be used in case you are not able to find the message at the top.
