egardless of the outcome, the commanders were compelled to put their request into writing –– a task that fell to Roosevelt because, as the only non-general among the senior officer group, had less to lose career-wise. The eventual U.S. president drafted what is now known as the infamous Round-Robin Letter:

MAJOR-GENERAL SHAFTER. SIR: In a meeting of the general and medical officers called by you at the Palace this morning we were all, as you know, unanimous in our views of what should be done with the army. To keep us here, in the opinion of every officer commanding a division or a brigade, will simply involve the destruction of thousands.

There is no possible reason for not shipping practically the entire command North at once. Yellow-fever cases are very few in the cavalry division, where I command one of the two brigades, and not one true case of yellow fever has occurred in this division, except among the men sent to the hospital at Siboney, where they have, I believe, contracted it. But in this division there have been 1,500 cases of malarial fever. Hardly a man has yet died from it, but the whole command is so weakened and shattered as to be ripe for dying like rotten sheep, when a real yellow-fever epidemic instead of a fake epidemic, like the present one, strikes us, as it is bound to do if we stay here at the height of the sickness season, August and the beginning of September.

Quarantine against malarial fever is much like quarantining against the toothache. All of us are certain that as soon as the authorities at Washington fully appreciate the condition of the army, we shall be sent home. If we are kept here it will in all human possibility mean an appalling disaster, for the surgeons here estimate that over half the army, if kept here during the sickly season, will die.

This is not only terrible from the standpoint of the individual lives lost, but it means ruin from the standpoint of military efficiency of the flower of the American army, for the great bulk of the regulars are here with you. The sick list, large though it is, exceeding four thousand, affords but a faint index of the debilitation of the army. Not ten per cent are fit for active work.

Six weeks on the North Maine coast, for instance, or elsewhere where the yellow-fever germ cannot possibly propagate, would make us all as fit as fighting-cocks, as able as we are eager to take a leading part in the great campaign against Havana in the fall, even if we are not allowed to try Porto Rico. We can be moved North, if moved at once, with absolute safety to the country, although, of course, it would have been infinitely better if we had been moved North or to Puerto Rico two weeks ago. If there were any object in keeping us here, we would face yellow fever with as much indifference as we faced bullets. But there is no object.

The four immune regiments ordered here are sufficient to garrison the city and surrounding towns, and there is absolutely nothing for us to do here, and there has not been since the city surrendered. It is impossible to move into the interior. Every shifting of camp doubles the sick rate in our present weakened condition, and, anyhow, the interior is rather worse than the coast, as I have found by actual reconnoissance.

Our present camps are as healthy as any camps at this end of the island can be. I write only because I cannot see our men, who have fought so bravely and who have endured extreme hardship and danger so uncomplainingly, go to destruction without striving so far as lies in me to avert a doom as fearful as it is unnecessary and undeserved.

Yours respectfully, THEODORE ROOSEVELT, Colonel Commanding Second Cavalry Brigade.

Signed by all the officers, the letter was delivered to Shafter and meant for delivery to the Army Headquarters in Washington.
