The Sirens of Siloam

Chapter 1 — A Solitaire Conflict System Campaign

The Vangarian army has landed on the beaches of Siloam. As the newly appointed commander of the allied forces, you must lead a desperate defense against a superior enemy — all while knowing that some on your own side are ready to betray you the moment things go south. A solo hex-and-counter campaign where every decision shapes the war and no two playthroughs are alike.

About the Designer

Henri Whitehead

Henri Whitehead

Educator • Wargamer • Designer

Based in Southwest Missouri and working at a community college by day. Outside the classroom, he keeps busy with plenty of hobbies both indoor and outdoor — but his real passion is board games, and historical wargaming sits at the top of that pile.

It started with Combat Commander. One play and the hobby had its hooks in. Since then, the goal has been straightforward: make wargaming less intimidating without watering it down. Take what makes hex-and-counter games rewarding and strip away the reasons people bounce off them. The Solitaire Conflict System is that effort — a streamlined solitaire opponent that brings tactical depth to large-scale hex-and-counter wargames, deep enough to satisfy and clean enough to actually get to the table.
