Kingstown and the Easter Rising

The Royal Navy doesn't get too much of a mention when it comes to the Easter Rising.

I'd like to find out more about the setup, ships etc that were in Kingstown (especially HMY Helga) at the time of the Rising and so have been delving into a number of books and websites (most of which give more information about Queenstown as centre of operations for the Royal Navy).

"The Sea Hound" appears to have the most answers re what the Navy had in Kingstown.

Some of the books I've read in the hope of understanding the Easter Rising in general and trying to get some information on the role of the Royal Navy include

The shelling of the Volunteers in Galway by HMS Laburnum took place as they approached the DATI experimental farm. Ironically, the naval shelling in Dublin was undertaken by HMY Helga, a ship built for the DATI.
