"Intelligence" (in the espionage sense) - first use?

According to Etymonline, the usage seems to pre-date the 1580s (assuming the agent noun came after the mass noun with the corresponding sense):

intelligencer (n.)

1580s, "spy, informant," agent noun from intelligence.

Meaning "bringer of news" is from 1630s; as a newspaper name from 1640s.

Indeed, Etymonline actually gives the 1580s as the time the 'military intelligence' sense originated. I'd assumed it didn't, as this now becomes general reference.
