Karna Parva is the seventy third Upa parva in the eighth Maha parva named as Karna Parva. The Karna Mahaparva has only one Upa parva, Karna Upa parva. Vaishampayana continued narration to Janamejaya in reply to his queries as follows.
एको हि योगोऽस्य भवेद्वधाय चिद्रे ह्येनं स्वप्रमत्तः प्रमत्तं ।
कृच्च्रप्राप्तं रथचक्रे निमग्ने हन्याः पूर्वं त्वं तु संज्ञां विचार्य ॥
After killing of Ghatotkacha, Krishna had appreciated Karna. He then told to Arjuna, the only chance available for Arjuna to kill Karna would be when Karna was puzzled but Arjuna was not puzzled, and while his chariot wheel is immersed in mud, I shall signal you. Please remember tomorrow, on the fifteenth day evening.
As commander-in-chief for the Kaurava army, how many days did Karna fight?
तयोर्द्वे दिवसे युद्धं कुरुपांडव सेनयोः। कर्णे सेनापतौ राजन्नभूदद्भुतदर्शनं ॥
As commander-in-chief for the Kaurava army, Karna had fought for two days, from the fourteenth day till the fifteenth day evening. Karna had showed wonderful capabilities.
‘But on the fifteenth day evening, in the war between the Kaurava and Pandava armies, O king, Karna had died’, Sanjaya told to Dritarashtra. Arjuna was fighting just for the namesake only but the actual killing was done by Agni that was moving in front of Arjuna described by Vyasa as below.
