[inquest]

as commander-in-chief, the king could declare war.

Now, as king he could declare war. As commander in chief, he could command the country's military. Are you really confused about this?

[Boot Hill]

inquest:   "as king he could declare war. As commander in chief, he could command the country's military"

The circular logic of inquest...

1. The king was commander-in-chief.

2. The king could declare war.

3. The commander-in-chief could not declare war.

4. Yet the commander-in-chief was the king!
