HAVANA, May 21.-Gen. Salcedo telegraphs from Santiago de Cuba that a fight occurred yesterday with a party of 700 insurgents between Dijas and Dos Rios, on the right bank of the River Contramaestre.

The insurgents were under command of Marti, Gomez, Masso, and Berrero, and the Spanish troops were led by Col. Sandoval. The fighting was severe, and lasted an hour and a half. The enemy was put to flight, and José Marti, who styles himself President of the republic, was killed. His body was captured and identified.

The loss on the insurgent side was fourteen known as killed and many wounded. All the correspondence of Marti was captured. Eleven horses with equipment were also captured.

On the Spanish side five were killed and seven wounded. Prisoners say that Gomez was killed or wounded, but that has not been corroborated. Gen. Campos left yesterday for the east.

José Marti and Gen. Maximilian Gomez, the insurgent leaders, were last reported to be proceeding westward toward Rompe. They had an encounter with Government troops several days ago at Camazan, near Holguin. After a fight which lasted several hours the insurgent forces withdrew. During the battle Col. Arizon of the Spanish forces was wounded.

Captain-General Campos visited Matanzas and Cienfuegos on his way to the eastern district.

SANTIAGO DE CUBA, May 9, via, Key West, May 21.-Gen. Campos has removed Graino, the head Custom house officer here. It is alleged that he has committed grave frauds.

The insurrection is making rapid progress. The Government has sent 10,000 troops in an endeavor to stop its extension westward. Spain is asked to send additional troops. Many prominent whites are joining Maceo from here, Manzanillo, and other cities.

WASHINGTON, May 21-The State Department has been informed that the Spanish Government has acceded to the request of the United States that "General" Sanguilly, an American citizen, arrested in Cuba for alleged complicity in the insurrection, receive a civil trial.

The United States presented a strong case to Spain, maintaining that no citizen of this country might be tried by a military tribunal unless captured with arms in his hands. The request for a transfer from military jurisdiction really amounted to a demand. The matter has some bearing on the case of ex-Consul Waller, who was tried and sentenced by a French military court in Madagascar, as it indicated that the State Department will insist that Waller shall be tried by a civil court.
