What became of the Southampton Tugs

what became of the 3 tugs that took the Titanic out of Southampton?and what became of the tenders America and Ireland?sorry if it is a strange question to ask but im interested.
I only know of the Tug Vulcan and i think she survived into the 1950s possibly the 1960s.

The America (1891, 262GT, 132 FT).
Bought by Anchor Line in 1928 for use on Lough Foyle. Used on the Clyde during WW2
Broken up in April of 1946 at Port Glasgow.

I have a pic of the America at the breakers.
