On August 4, at the recommendation of the Nicaraguan president, a landing force of 100 bluejackets was dispatched from Annapolis to the capital, Managua, to protect American citizens and guard the U.S. legation during the insurgency.
On the east coast of Nicaragua, the USS Tacoma (CL-20) (a protected cruiser from the American North Atlantic Fleet) was ordered to Bluefields, Nicaragua, where she arrived on August 6 and landed a force of 50 men to protect American lives and property.
A force of 350 U.S. Marines shipped north on the collier USS Justin from the Canal Zone and disembarked at Managua to reinforce the legation guard on August 15, 1912.
Under this backdrop, Denver and seven other ships from the Pacific Fleet arrived at Corinto, Nicaragua, from late August to September 1912, under the command of Rear Admiral W.H.H. Southerland.

USS Denver, commanded by Commander Thomas Washington arrived at Corinto on August 27, 1912, with 350 navy bluejackets and Marines on board.
Admiral Southerland's priorities were to re-establish and safeguard the disrupted railway and cable lines between the principal port of Corinto and Managua, 110 kilometres (70 mi) to the southeast.

On August 29, 1912, a landing force of 120 men from USS Denver, under the command of the ship's navigator, Lieutenant Allen B. Reed, landed at Corinto to protect the railway line running from Corinto to Managua and then south to Granada on the north shore of Lake Nicaragua.
This landing party reembarked aboard ship October 24 and 25, 1912.
One officer and 24 men were landed from the Denver at San Juan del Sur on the southern end of the Nicaraguan isthmus from August 30 to September 6, 1912, and from September 11 to 27, 1912 to protect the cable station, custom house and American interests.
Denver remained at San Juan del Sur to relay wireless messages from the other navy ships to and from Washington until departing on September 30, for patrol duty.

On the morning of September 22, two battalions of Marines and an artillery battery under Major Smedley Butler, U.S.M.C. had entered Granada, Nicaragua (after being ambushed by rebels at Masaya on the nineteenth), where they were reinforced with the Marine first battalion commanded by Colonel Joseph H. Pendleton, U.S.M.C.. General Mena, the primary instigator of the failed coup d'etat surrendered his 700 troops to Southerland and was deported to Panama.
Beginning on the morning of September 27 and continuing through October 1, Nicaraguan government forces bombarded Barranca and Coyotepe, two hills overlooking the all-important railway line at Masaya that Zeledón and about 550 of his men occupied, halfway between Managua and Granada.

On October 2, Nicaraguan government troops loyal to President Diaz delivered a surrender ultimatum to Zelaydón, who refused.
Rear Admiral Southerland realized that Nicaraguan government forces would not vanquish the insurgents by bombardment or infantry assault, and ordered the Marine commanders to prepare to take the hills.

On October 3, Butler and his men, returning from the capture of Granada, pounded the hills with artillery throughout the day, with no response from the insurgents.
In the pre-dawn hours of October 4, Butler's 250 Marines began moving up the higher hill, Coyotepe, to converge with Pendletons's 600 Marines and landing battalion of bluejackets from California.
At the summit, the American forces seized the rebel's artillery and used it to rout Zeledón's troops on Barranca across the valley.

Zeledón and most of his troops had fled the previous day during the bombardment, many to Masaya, where Nicaraguan government troops captured or killed most of them, including Zeledón.
With the insurgents driven from Masaya, Southerland ordered the occupation of Leon to stop any further interference with the U.S.-controlled railroad.
On October 6, 1,000 bluejackets and Marines, from the cruisers USS California, USS Colorado, and Denver led by Lieutenant Colonel Charles G. Long, U.S.M.C. captured the city of Leon, Nicaragua, the last stronghold of the insurgency.
