301 redirect issue

I have some 404 links coming up on an old directory and some directories inside that one as well… So I get 404 hits still going to /v1/ and /v1/another-folder/ etc.

What I wrote below takes care of /v1 but not if there’s a trailing slash, and not for anything else beyond /v1/…

In my .htaccess file I have the following:

# 301 Permanent Redirects
Redirect 301 /v1 http://domain.com/

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

How do I fix that? TY!
