The Italian offensive lasted two weeks and largely failed.  It was followed by four months of Greek counter-offensive and stalemate. By the Spring, both sides were too weak to launch a major new attack.  It was left to Germany to settle the matter in April 1941.

The Greco-Italian War has maps detailing the different offensives.
