Campaign Map on 20 September 1813
Giron ordered his army to retreat to Molina
All four corps have used their last supplies to do so
They will suffer attrition casualties until they have been able to resupply
Suchet ordered his army to halt, resupply and regroup
All four corps receive supplies and now have four days per corps
His routed brigades are rallied
Replacements for his battle casualties start to arrive
The French have won the campaign, but are too battered to pursue the Spanish
Suchet arranged for his battered army to be resupplied, and wrote a report to Napoleon claiming a total victory against the Spanish field army. However he is well aware that the final battle was a close run thing, which could easily have resulted in a Spanish victory.
At the end of the battle of Hellin both armies were fought to a draw. Both had considerable battle casualties. Both had used all of their reserves.
However the French were within range of four depots, including their main depot at Albacete. They ended the day with two days supplies per corps, and could easily restock the following day providing they did not have to fight again. Even if they did, they would still be in supply.
The Spanish were a long way from their three supply bases. They were also down to one days supply per corps when the battle ended. If required to fight the next day they would end that day out of supply. Even if they won the battle they would start to lose attrition casualties (10% of one brigade per corps) for each day until they resupplied. To do so they would have to retreat south towards their bases.
The Spanish had lost considerably more casualties than the French, and had almost twice as many brigades in rout. In addition almost all of their remaining brigades had at least 10% casualties. They would start a second day of battle outnumbered by the French, and would have to renew the attack to take at least the other half of the town.
The French also had considerable casualties. They had lost half of their cavalry and all of their remaining brigades also had battle casualties. But they were on the defensive, and well positioned to hold for another day.
It was the Spanish who blinked first. Faced with the destruction of his entire Army, General Giron ordered the retreat.
