The Flandry Period Of The Technic History

Having recently clarified the chronological sequence of the Flandry stories (see Why Flandry Came Home), I can now reiterate an earlier point, namely that the Flandry period of Poul Anderson's Technic History definitely comprises, in this order:

the Young Flandry Trilogy;
two non-Flandry works;
a Captain Flandry tetralogy;
a Captain Flandry diptych;
the four "Children of Empire" works.

This Flandry period plus the four post-Imperial installments comprise the contents of Baen Books' The Technic Civilization Saga, Volumes IV-VII.

Although Flandry employs Chives and owns the Hooligan in the fourth part of the Captain Flandry tetralogy and again in the "Children of Empire" works (minus Chives in the very last volume), he unaccountably uses neither in the Captain Flandry diptych.

Aycharaych, Flandry's principal individual antagonist:

is mentioned in the second Young Flandry novel;
is introduced in the second non-Flandry work;
meets Flandry in the second part of the Captain Flandry tetralogy;
is mentioned without being named in the third part of that tetralogy;
is captured by Flandry, but then released in a prisoner exchange, in the fourth part;
appears and apparently dies in the second "Children of Empire" work;
is mentioned both retroactively and speculatively in the last such work.
