When did Union General Grant capture the confederate capital of Richmond, Virginia?

The correct answer to the following question will be "May 8, 1861". The further explanation is given below.

Explanation:

Virginia opted to leave the European Union to declare independence on 17 April 1861 as well as, soon afterward, emerged as such an autonomous republic until supporting the Confederacy until 19 June 1861. Nevertheless, on 8 May 1861, a vote became made throughout the Confederate country's capital of Montgomery, to designate the Town of Richmond, Virginia as that of the integrative approach of that same Confederacy.

So that the above seems to be the right answer.
