Two groups of Chinese miners, led by Chea Po and Lee She, departed Lewiston in October 1886 and headed upriver along the Snake into Oregon's Hells Canyon to search for gold.

Chea Po had chosen a location just upstream of Dug Bar, a ford used by horse and cattle thieves to cross the Snake.

(Homer) LaRue, Frank Vaughn, Carl (or Hezekiah) Hughes, Hiram Maynard and Robert McMillan, a fifteen-year-old boy.

After the first day's onslaught at Robinson Gulch, the killers wrecked and burned the camp and then threw the mutilated corpses into the Snake River.

Since it was the high-water stage of the spring runoff, the dead Chinese were found for months (some accounts say for years) afterwards along the lower river.Robert McMillan made a deathbed confession to his father Hugh recounting details of the massacre, which were published in 1891.

Canfield and Larue first attacked the camp of thirteen Chinese from the bluffs overlooking the cove, driving them towards Evans and Vaughn, who were in the path of their retreat.

The next day, eight more Chinese returned to the camp by boat, where the gang shot and killed them, throwing the 21 bodies into the Snake River.

[7] The bodies of some murder victims began washing ashore soon afterward, swept downstream to places as far away as Lime Point (south of the mouth of the Grande Ronde River), Log Cabin Island (now the site of the Lower Granite Dam), and Penawawa, Washington.

Each body bore unmistakable markings of great violence; J.K. Vincent, a federal official who investigated the crime, later wrote "every one was shot, cut up and stripped and thrown in the River.

"[10] George S. Craig owned the Douglas cabin and discovered numerous skeletons in the area when he returned to winter his stock in the fall of 1887.

[11] In follow-up testimony given on April 16, Vaughn blamed Evans, Canfield, and LaRue for the massacre, and said that he, Hughes, Maynard, and McMillan had not participated.

[11] In 1995, Charlotte McIver discovered a cache of documents relating to the 1888 trial in an old safe being donated to the Wallowa County Museum.

Deep Creek, a fictionalized account of the massacre and its aftermath written by William Howarth and Anne Matthews under the pen name "Dana Hand" was published in 2010.

[18] In 2012, Nokes organized the Chinese Massacre Memorial Committee (with private funds and donations) to install a granite monument measuring 4 by 5 feet (1.2 by 1.5 m) in May 2012.
