 of Echizen. The Asakura and Azai had been allies since the time of Nagamasa's grandfather. This sudden war between two Azai clan allies is reported to have divided the clan. Many retainers wished to honor the alliance with the Asakura, while Nagamasa himself is reported to have favored staying neutral, essentially siding with Nobunaga. In the end, the Azai clan chose to honor the generations-old alliance with the Asakura and came to their aid. Initially, this decision caused Nobunaga's army, which was marching upon the Asakura's lands to retreat back to Kyoto. However, within a few months the forces of Nobunaga were again on the march, but this time they marched on Azai lands.

In the summer of 1570, Oda Nobunaga and Tokugawa Ieyasu

. The combined Azai and Asakura force numbered between 15-20,000 men. The outcome is recorded elsewhere, but briefly: The battle was strongly contested by both sides. Nobunaga is recorded as having decided that his force should directly confront the numerically inferior Azai clan force, while Ieyasu would engage the Asakura. While the Oda were being held at bay, and perhaps even slowly losing ground to the Azai - who had fought against numerically superior forces in the past - Ieyasu's force was apparently quickly gaining the advantage against the Asakura. Ieyasu, or perhaps one of his battle commanders, decided to send part of the Tokugawa force into the Azai flank, forcing the Azai to retreat, and guaranteeing victory. However, the battle was strategically indecisive because the Oda shortly withdrew.

Over the course of the next two years, with the exception of occasional interventions by the Shogun, Azai Nagamasa was under constant threat of Nobunaga aggression into Omi. Often these threats manifested into sieges of the Azai Capitol, Odani. During this period the Azai are seen as being loosely aligned with numerous anti-Oda forces, including the Asakura, the Miyoshi, the Rokkaku, and several religious complexes.

In 1573, Oda laid siege to Odani
Odani Castle

. Although the Asakura sent a relief force, Nobunaga defeated this force and chased the Asakura into their lands. Shortly thereafter, the Asakura were destroyed. Nobunaga then returned south to prosecute the siege of Odani. Nagamasa had no hope of winning, and chose to commit seppuku
Seppuku

. Before dying, he and his wife Oichi sent out their two sons to be hidden in far off place that only they knew of, while he sent out his three daughters and his wife, Nobunaga's sister, to live with Nobunaga. They were allowed to live. Later on, Oda convinced Oichi to tell him where she had sent her infant son Manpukaru saying that he wanted the boy to live with and raise him. Nagamasa's male heir, Manpukumaru, was put to the sword on Oda Nobunaga's orders by his general Hideyoshi and the head be put on a stake for all to see. Oda made sure no one told his sister, Oichi of this but soon after, since she hadn't heard word of her son yet, came to that suspicion. There are reports that Nobunaga bore a strong grudge against Nagamasa for his perceived betrayal of their alliance even though it was he who broke the agreement first. It has also been reported that Nobunaga had the skulls of Nagamasa, Hisamasa, and the Asakura leader lacquered so that they could be used as cups. Whether this report is historically accurate, or merely made up to inflate the reputation of Nobunaga is debatable at this time.
