"Friends, what a fine piece of work he’s carried off!
Telemachus – what insolence – and we thought his little jaunt
would come to grief! Up now, launch a black ship,
the best we can find – muster a crew of oarsmen,
row the news to our friends in ambush, fast,
bring them back at once."

– Homer

The Odyssey, Book 16, lines 382-387. Eurymachus makes this speech on learning that Telemachus has twarted the murderous suitors and made it safely home to Ithaca. Telemachus has succeeded in avoiding the ambush set up by the suitors and this has surprised and shaken them. Eurymachus issues a call to bring back the plotters who are waiting to ambush Telemachus. This is an example of situational irony, because what happens is the opposite of what people expected.
