Why did Lord Krishna run away unable to fight Jarasandhu?

 Jarasandha had many allies, as Krishna mentions

Jarasandha has inherited the empire by birth and that king’s influence extends everywhere. O king! O great king! The powerful Shishupala has gone to him like a disciple and has become his general. Vakra, the immensely strong king of Karusha, who fights with the powers of maya, and many other immensely valorous and great- souled ones, are also under his protection. The illustrious Hamsa and Dibhaka are also with the immensely valorous Jarasandha.

Likewise, the evil king of the Chedis, whom I did not kill earlier, has also gone over to Jarasandha. He who is known in the world as the supreme being and out of delusion, always bears my signs. There is also a king powerful in Vanga, Pundra and Kirata, known as Vasudeva of Pundra. O great king! There is also the powerful Bhishmaka Chaturyu of Bhoja, a friend of Indra’s and a slayer of enemies. Through his learning and strength, he has conquered Pandya and Krathakaishika. The valorous Ahriti is his brother and is like Jamadagni Rama in battle. They also serve the king of Magadha.

~ Mahabharata, Sabha Parva, Mantra Parva, Chapter 238(13)

The ones mentioned over here were Shishupala who is the king of Chedi, Dantavakra who is the king of Karusha, Poundraka Vasudeva, Bhishmaka who is Rukmini’s father and Ahriti who is the brother of Bhishmaka are the main allies of Jarasandha and he had many others under his wing. And Shurasena was on a plain area without any natural barriers so that they can have some advantage like Magadha which was between hills

‘Vasudeva said, “O Partha! This is the great and beautiful city of Magadha. It is rich in cattle and is always full of water. It is prosperous and has no disease and has many splendid mansions. O tata! There are five large mountains, the extensive Vaihara, Varaha, Vrishabha, Rishigiri and the beautiful Chaitya. These five giant mountain peaks are covered with trees with cool shade and though separate, seem to collectively protect Girivraja.

~ Mahabharata, Sabha Parva, Jarasandha-Vadha Parva, Chapter 244(19)

So to protect themselves from those constant attacks and also to live in an area with natural barriers and prevent these attacks altogether, they shifted to Dwaraka. Krishna could’ve killed Jarasandha had he desired but he didn’t do so as Bhima was destined to kill him

It had been destined that Jarasandha would be killed by the valorous Bhima. Madhusudana, the younger brother of Haladhara, foremost among those who have controlled themselves, wished to show respect to Brahma and did not wish to kill him himself.

~ Mahabharata, Sabha Parva, Jarasandha-Vadha Parva, Chapter 245(20)

Also he can do anything he wishes, but since he was in a human form he behaves like one. So this fleeing of Yadavas must not be seen in a wrong way and incompetence.

In a desire to ensure the welfare of subjects, I enter various wombs. O descendant of the Bhrigu lineage! When I am born in a divine womb, there is no doubt that I follow all the acts followed by the gods. O descendant of the Bhrigu lineage! O Bhargava! In that way, when I am born in the womb of a gandharva, I then make all the efforts that are made by gandharvas. When I am in the womb of a serpent, I then behave like a serpent. When I am born in the wombs of yakshas and rakshasas, I then follow their kinds of conduct. Since I am now a human, I beseeched them piteously.

~ Mahabharata, Ashwamedha Parva, Chapter 1888(53)

So even fleeing, acting as messenger, doing poilitics etc are also his lilas as he was in a human form

This is merely the divine play of the Lord of the Universe acting in accordance with human nature, when He hurls weapons of various forms against His enemies. For Him who creates and destroys the entire universe merely by His will, what need is there for such elaborate effort to annihilate the side of His enemies? Even so, He follows the duties and conduct suitable for human beings; He makes with those who are powerful and engages in battle with those who are weaker. Demonstrating conciliation (Sama), giving gifts (Dana), causing dissension (Bheda), inflicting punishment (Danda), and even fleeing at times in this manner, as He follows the actions and behaviors of embodied human beings, the divine play of the Lord of the Universe proceeds entirely according to His own free will.

~ Vishnu Purana, Amsha 5, Chapter 22

Why was it so crucial for Krishna and the Pandavas to defeat Jarasandha before attempting the Rajasuya sacrifice?

If Pandavas had faced Magadh army under emperor Jarasandha’s rule, they would've been effortlessly crushed like bugs.

Krishna himself along with Balarama, Satyaki, Pradyumna and whole of Yadavs combined couldn't do anything against Magadh's full might under Jarasandha..

He had unique boon from Rishi Chandakaushik to be invulnerable to weapons. 2 of his army generals named Hamsa and Dimvaka had same exact boon. In addition to this he gained many boons from Shiva which helped him conquer all countries in the contemporary world barring Hastinapura and Dwaraka. Hastinapura was spared due to Bhishma and Dwaraka was setup in Mountainous regions inaccessible to him.

Krishna to Yudhistira: -

It behoveth thee, O Bharata, to establish thy empire over all the Kshatriyas. But this is my judgment, O king, that thou wilt not be able to celebrate the Rajasuya sacrifice as long as the mighty Jarasandha liveth. By him have been immured in his hillfort numerous monarchs, like a lion that hath deposited the slain bodies of mighty elephants within a cave of the king of mountains.

..

By defeating the kings with their troops and bringing all of them as captives into this city, he had swelled its crowds enormously. We also, O king, from fear of Jarasandha, at one time had to leave Mathura and fly to the city of Dwaravati.

If, O great king, thou desirest to perform this sacrifice, strive to release the kings confined by Jarasandha, as also to compass his death. O son of the Kuru race, otherwise this undertaking of thine can never be completed. O thou foremost of intelligent men if the Rajasuya is to be performed by thee, you must do this in this way and not otherwise.

Further he stated that Jarasandha is too tough to be beaten in a war, even by Dev's and Asuras (obviously a hyperbole). And therefore be subdued in a personal combat where his army or allies won't interfere.

He is incapable of being vanquished in battle even by all the celestials and the Asuras (fighting together). We think, however, that he should be vanquished in a personal struggle with bare arms. In me is policy, in Bhima is strength and in Arjuna is triumph; and therefore, as prelude to performing the Rajasuya, we will certainly achieve the destruction of the ruler of Magadha. When we three approach that monarch in secret, and he will, without doubt, be engaged in an encounter with one of us.

From fear of disgrace, from covetousness, and from pride of strength he will certainly summon Bhima to the encounter. Like death himself that slays a person however swollen with pride, the long-armed and mighty Bhimasena will effect the destruction of the king.

That could be mythological reasoning. Realistically, Jarasandha simply could've been an unparalleled military intellect under whose command Magadh empire was unbeateable.

Jarasandh by himself was merely immune to weapons but was vulnerable to defeat in physical combat. But under his leadership, Magadh was Strongest military force in that era.

Jarasandha's Most Significant Battles in the Mahabharata: A Detailed Analysis

Introduction

Jarasandha, the powerful ruler of Magadha, was one of the most formidable antagonists in the Mahabharata. He was the son of King Brihadratha and was born under miraculous circumstances, having been joined together by a rakshasi named Jara. Jarasandha’s prowess as a warrior and his vast empire made him one of the most influential kings of his time. His military campaigns and conflicts with the Yadavas, Pandavas, and other rulers were pivotal in shaping the course of history in the Mahabharata.

This analysis delves into Jarasandha’s most significant battles, his strategic strengths, and the ultimate confrontation that led to his downfall.

1. Jarasandha’s Military Strength and Conquests

Jarasandha was known for his extensive military might. His army was vast, consisting of numerous chariots, cavalry, elephants, and infantry. His capital, Rajagriha, was heavily fortified, making it difficult for enemies to attack. His primary ambition was to establish himself as the undisputed emperor by subjugating rival kingdoms.

2. Conflict with the Yadavas

One of Jarasandha’s most significant rivalries was with the Yadavas, particularly Lord Krishna and his allies. His enmity with them stemmed from his son-in-law, Kansa, who was slain by Krishna.

2.1 Battle Against Krishna in Mathura

Jarasandha sought vengeance for Kansa’s death and launched a series of attacks against the city of Mathura, where Krishna and the Yadavas resided.

• First Attack: Jarasandha led a massive army against Mathura. Krishna and Balarama, though outnumbered, managed to defend the city using superior tactics. Jarasandha was forced to retreat.
• Repeated Invasions: Jarasandha attacked Mathura seventeen times, each time gathering a larger army. However, Krishna and Balarama consistently repelled his attacks through guerrilla warfare and defensive strategies.
• Final Assault and the Exodus to Dwaraka: Realizing that Mathura was becoming indefensible due to constant invasions, Krishna decided to shift the Yadava capital to Dwaraka. This strategic move deprived Jarasandha of his primary target, frustrating his attempts to annihilate the Yadavas.

3. The Battle Against Kalayavana and the Yadava Strategy

Jarasandha later allied with Kalayavana, a powerful barbarian king, to destroy Krishna. Kalayavana led an independent attack on Mathura, while Jarasandha planned another assault. Krishna, using his intelligence, lured Kalayavana into a cave where he was killed by the sage Muchukunda. This event weakened Jarasandha’s offensive strategy, forcing him to abandon his plan.

4. Conquest of Northern and Central Indian Kingdoms

Jarasandha sought to expand his empire and aimed at performing the Rajasuya Yajna by imprisoning and sacrificing 100 kings. He subjugated several kingdoms, including:

• Chedi (Shishupala’s Kingdom)
• Kashi (Varanasi)
• Kalinga (Odisha region)
• Kosala
• Panchala
• Mithila His ambition to establish absolute supremacy led to tensions with the Pandavas, particularly Yudhishthira, who also aspired to perform the Rajasuya Yajna.

5. The Final Battle: Jarasandha vs. Bhima

One of the most legendary battles in the Mahabharata was Jarasandha’s duel with Bhima, orchestrated by Krishna as part of the Pandavas’ Rajasuya Yajna preparations.

5.1 Krishna’s Strategy to Weaken Jarasandha

• Yudhishthira’s desire to perform the Rajasuya Yajna required all rival kings to either submit or be defeated.
• Krishna, knowing that a full-scale war against Magadha would be costly, devised a plan to challenge Jarasandha in a one-on-one duel.
• Krishna, Bhima, and Arjuna disguised themselves as Brahmins and entered Rajagriha, where they challenged Jarasandha to combat.

5.2 Bhima vs. Jarasandha: The Epic Duel

• Jarasandha, known for his warrior code, agreed to single combat with Bhima.
• The battle lasted for fourteen days, with both warriors showcasing immense strength and endurance.
• Despite being evenly matched, Bhima, under Krishna’s guidance, tore Jarasandha’s body apart and threw the two halves in opposite directions, preventing his body from rejoining, thereby killing him permanently.

6. Aftermath and Impact of Jarasandha’s Death

• With Jarasandha’s demise, the imprisoned kings were freed, and Yudhishthira successfully completed his Rajasuya Yajna.
• Magadha’s throne was handed over to Sahadeva, Jarasandha’s son, who allied with the Pandavas.
• The removal of Jarasandha’s threat allowed Krishna and the Pandavas to focus on other powerful adversaries like Duryodhana and Shakuni.

Conclusion

Jarasandha’s battles were among the most significant conflicts in the Mahabharata. His repeated invasions of Mathura, his expansionist campaigns, and his final confrontation with Bhima highlight his role as a formidable warrior and a key political player of the era. His death marked a turning point, paving the way for the Pandavas’ rise and the eventual Kurukshetra War. His military strategies, strengths, and weaknesses offer valuable insights into the dynamics of ancient Indian warfare and diplomacy.
