Basically chronologicl:

"It is reliably stated that United States Marshal Dake will place in the hands of proper authorities a sufficient amount of funds for the organization and equipping of a body of men for service in and about Tombstone, and whose special duty will be extirpation of stage robbers, cattle thieves and lawlessness in general. - Citizen"
[Epitaph - Jan. 26, 1882, p. 4]

Meanwhile Dake had already funded Earp earlier in the month:

"Prospects are good in Arizona for a bloody combat between a party of cowboys and a United States Marshal’s posse…. Tucson, January 24th. -The Tombstone Nugget publishes the following:
“There was considerable excitement on the streets yesterday, occasioned by the departure from town of Wyatt and Morgan Earp, Doc. Holliday, Texas Jack and three of their retainers, whose names we did not learn. They rode up Allen street, going east, while the side walks were crowded with throngs of citizens speculating upon their probable destination. Each of the horsemen were armed with a shotgun, Winchester rifle and two revolvers, and at least 100 rounds of ammunition. All sorts of rumors were rife upon the streets during the afternoon and evening, but until 6 o'clock no one knew to a certainty which direction, after leaving the city, the horsemen had taken..... The cowboys, in addition to their well-known fighting proclivities, are in this instance animated by a thirst for revenge, and the Earp party is composed of desperate men, who will each fight to the death, and it is stated that they have all been sworn in as Deputy United States Marshals, in which case they will have the color of law under which to act. The ultimate destination of the Earp party yet remains unknown to the majority of our citizens. Some think they went out as a United States Marshal's posse comitatus in search of lawless characters, while others are of the opinion that they are making an attempt to leave the country, the latter class being in a large majority.""

Evidently, in addition to the Earp-led posse Dake was to appoint a supplemental DUSM for same purpose, and to make it official at Tombstone:

"The Deputy Marshalship.
In conversation with Marshal Dake yesterday, we were informed by him after a careful consideration of the question, and having only one appointment to make, he had selected Mr. J.H. Jackson for the position, and that immediately upon his return to Prescott a commission would be forwarded…..
During Marshal Dake’s visit to Tombstone he has zealously endeavored to ascertain not only the public conviction regarding the situation in Cochise, but doubtless also equally important facts that are known only to the secret service department of the government, and acting under a better knowledge and, with more facts before him than citizens have, the general public are satisfied that Mr. dake will conscientiously perform his duty in an earnest endevore to bring criminals to justice and peace and harmony to our country."
[Epitaph - Feb. 3, 1882, p. 2]

"Marshal C.P. Dake who has made a good officer, barring some of his appointments of Deputies, is home again from San Francisco and Sothern Arizona."
[Weekly Journal Miner - Feb. 10, 1882, p. 3]

"….Now, in the face of a possibility of personal loss, Maj. Dake has placed $3,000 in the bank of Tombstone, to be used in raising forces for the suppression of lawlessness in southern Arizona, trusting that an act of congress will relieve him and place the amount to his credit at an early day. Fifteen hundred of the $3,000 have already been used by the deputy marshals in putting down the cow-boy disturbances. Major Dake has paid his juries, deputies, and all court expenses promptly; and, in fact made the best marshal Arizona has ever had…."
[Epitaph - Feb. 21, 1882, p. 2]

"In regard to the troubles in Cochise county, we are informed by Marshal Dake that the difficulty with his department is not so much a lack of funds as a want of authority to use them. The United States Marshal has no authority to expend government money to raise a posse to hunt cow boys or other malefactors unless they have committed offenses against the United States. He says that a special act must be passed empowering him to pursue the cattle thieves of Cochise."
[Epitaph - Feb. 27, 1882, p. 6]

"In resisting arrest the Earp clan have committed another offense against the law, which goes to show the character of the officials Tombstone was encumbered with, and to whom Marshal Dake has yielded too long. We under stand that this gang are still acting as United States officials. It will not be very cheerful news to the Department. Of Justice at Washington that a posse a posse of its Deputy Marshals are refugees from justice."
[Arizona Weekly Star - March 23, 1882, p. 2]
