Fabian strategy

The Fabian strategy is a military strategy where pitched battles and frontal assaults are avoided in favor of wearing down an opponent through a war of attrition and indirection. While avoiding decisive battles, the side employing this strategy harasses its enemy through skirmishes to cause attrition, disrupt supply and affect morale. Employment of this strategy implies that the side adopting this strategy believes time is on its side, but it may also be adopted when no feasible alternative strategy can be devised.

This strategy derives its name from Quintus Fabius Maximus Verrucosus, the dictator of the Roman Republic given the task of defeating the great Carthaginian general Hannibal in southern Italy during the Second Punic War (218–202 BC). At the start of the war, Hannibal boldly crossed the Alps in wintertime and invaded Italy. Due to Hannibal's skill as a general, he repeatedly inflicted devastating losses on the Romans despite the numerical inferiority of his army—quickly achieving two crushing victories over the Romans at the Battle of Trebbia and the Battle of Lake Trasimene. After these disasters the Romans appointed Fabius Maximus as dictator. Well aware of the military superiority of the Carthaginians and the ingenuity of Hannibal, Fabius initiated a war of attrition which was designed to exploit Hannibal's strategic vulnerabilities.

Hannibal suffered from two particular weaknesses. First, he was commander of an invading foreign army on Italian soil, effectively cut off from the home country by the difficulty of seaborne resupply. His only hope of destroying Rome was by enlisting the support of her allies. As long as the Italians remained loyal to Rome, then there was no hope that Hannibal would win; but should the Romans keep on losing battles, their allies' faith in Rome would weaken. Therefore, Fabius calculated that the way to defeat Hannibal was to avoid engaging with him in pitched battles, so as to deprive him of victories. He determined that Hannibal's extended supply lines, and the cost of maintaining the Carthaginian army in the field, meant that Rome had time on its side. Rather than fight, Fabius shadowed Hannibal's army and avoided battle, instead sending out small detachments against Hannibal's foraging parties, and maneuvering the Roman army in hilly terrain, so as to nullify Hannibal's decisive superiority in cavalry. Residents of small northern villages were encouraged to post lookouts, so that they could gather their livestock and possessions and take refuge in fortified towns. He used interior lines to ensure that at no time could Hannibal march on Rome without abandoning his Mediterranean ports, while at the same time inflicting constant, small, debilitating defeats on the North Africans. This, Fabius had concluded, would wear down the invaders' endurance and discourage Rome's allies from going over to the enemy, without having to challenge the Carthaginians to a decisive battle.
