Mainly because I'm on the other side...
Sir Francis Gamull's Trayned Band of the Cittie of Chyster.
Intending to either have Gamull and Mostyn's Regiments of foote supported by Chomondeley Horse (lead by Colonel John Marrow) OR perhaps the Irish Reinforcments (of which not one man was Irish, but a veteran of the Irish fighting - and the very people Brereton tried to convince to turn) that landed in Flint on 15 November 1643, placed under John Byron and then units parted ways after Nantwich on 25 January 1944 (well... Sir Michael Erneley and Maj-Gen Richard Gibson were brigaded together at Marston Moor and appear to have worked together before leaving Ireland).
Was there something specific about Brereton? Or just about the man in particular?
Some links I used on my research into the ECW goings on in and around chester:

And look at the pdf file on this site too.
I'd also suggest the book "The Great Seige of Chester" By John Barratt.
Much of the information online is found over and over again, but now and then there is a real nugget of information.
As for the accuracy of information, same as any other historical records.
If I do find anything else I will make a note and reference it here.
