In the wake of Italy's rapid annexation of Albania in April 1940, Mussolini's decision to attack Greece in October that year is widely acknowledged as a fatal mistake, leading to a domestic crisis and to the collapse of Italy's reputation as a military power (re-emphasized by the Italian defeat in North Africa in December 1940). The Italian assault on Greece came to a stalemate in less than a fortnight, and was followed a week later by a Greek counter-offensive that broke through the Italian defences before advancing into Albania, forcing the Italian forces to withdraw north before grinding to a half in January 1941 due to logistical issues. Eventually, the Italians took advantage of this brief hiatus to reorganize and prepare a counteroffensive, the failure of which marked the end of the first stage of the Axis Balkan campaign.
