Нагасима қоршауы: Ода Нобунага мен Икко-Икки арасындағы шайқастар

Series of sieges between Oda and Ikkō Ikki forces

The Sieges of Nagashima (長島一向一揆), taking place in 1571, 1573, and 1574, were part of Oda Nobunaga's campaigns against the Ikkō ikki, arguably among his greatest enemies. Nagashima, in Owari Province along Japan's Pacific coast, was the location of a string of river island fortresses and defensive works controlled by the Ikkō ikki, which surrounded their Ganshō ji monastery and which included Nagashima Castle, which they had captured previously. Oda Nobunaga attacked three times over the course of four years, before finally destroying the entire Nagashima complex. These sieges were executed concurrently with Nobunaga's eleven year siege against the Ikki's primary fortress of Ishiyama Hongan ji.

Nobunaga's troops made camp at Tsushima, to the northeast of Nagashima, on 16 May 1571. Separated from the Ikki's fortresses by a shallow but broad river. Nobunaga's commanders, Sakuma Nobumori and Shibata Katsuie, planned their attack upon the nearby wajū, small island communities from which attacks on Ganshōji could be launched. These islands were defended from flooding by a complex series of levees. Nobunaga's forces attacked across the river, but their horses became stuck in the soft mud of the river bottom. The samurai that managed to drag themselves to shore while being fired on were further slowed by ropes stretched across stakes, which tripped up their horses further. Many were then drowned when the defenders opened a dike and flooded the area. Katsuie was injured, Ujiie Naotomo killed and many samurai were lost; this first attempt was a definite failure for Nobunaga. His men did manage to set a few villages aflame, however, as they withdrew.
