rough our State Department, looking to the suppression of
the colony; but, as usual, nothing could be effected through that
channel; so, as an alternative, I published, in April, 1866, by
authority of General Grant, an order prohibiting the embarkation from
ports in Louisiana and Texas, for ports in Mexico, of any person
without a permit from my headquarters. This dampened the ardor of
everybody in the Gulf States who had planned to go to Mexico; and
although the projectors of the Cordova Colonization Scheme--the name
by which it was known--secured a few innocents from other districts,
yet this set-back led ultimately to failure.

Among the Liberal leaders along the Rio Grande during this period
there sprang up many factional differences from various causes, some
personal, others political, and some, I regret to say, from downright
moral obliquity--as, for example, those between Cortinas and Canales
--who, though generally hostile to the Imperialists, were freebooters
enough to take a shy at each other frequently, and now and then even
to join forces against Escobedo, unless we prevented them by coaxing
or threats. A general who could unite these several factions was
therefore greatly needed, and on my return to New Orleans I so
telegraphed General Grant, and he, thinking General Caravajal (then
in Washington seeking aid for the Republic) would answer the purpose,
persuaded him to report to me in New Orleans. Caravajal promptly
appeared, but he did not impress me very favorably. He was old and
cranky, yet, as he seemed anxious to do his best, I sent him over to
Brownsville, with credentials, authorizing him to cross into Mexico,
and followed him myself by the next boat. When I arrived in
Brownsville, matters in Matamoras had already reached a crisis.
General Mejia, feeling keenly the moral support we were giving the
Liberals, and hard pressed by the harassing attacks of Cortinas and
Canales, had abandoned the place, and Caravajal, because of
his credentials from our side, was in command, much to the
dissatisfaction of both those chiefs whose differences it was
intended he should reconcile.

The day after I got to Brownsville I visited Matamoras, and had a
long interview with Caravajal. The outcome of this meeting was, on
my part, a stronger conviction than ever that he was unsuitable, and
I feared that either Canales or Cortinas would get possession of the
city. Caravajal made too many professions of what he wo
