an expedition under Brigadier-General Pope to capture the town
of New Madrid as a preliminary step. Columbus and Nashville were almost
sure to fall as the result of Donelson. If now he could bring his two
Missouri campaigns into a combination with two swift and strong
Tennessee expeditions, while the enemy was in scattered retreat, he
could look forward to the speedy capture of Memphis. But to the
realization of such a project, the hesitation and slowness of Buell were
a serious hindrance. That general had indeed started a division under
Nelson to Grant's assistance, but it was not yet in the Cumberland when
Donelson surrendered. Halleck's demand for enlarged power, therefore,
became almost imperative. He pleaded earnestly with Buell:

"I have asked the President to make you a major-general. Come down to
the Cumberland and take command. The battle of the West is to be fought
in that vicinity.... There will be no battle at Nashville." His
telegrams to McClellan were more urgent. "Give it [the Western Division]
to me, and I will split secession in twain in one month." And again: "I
must have command of the armies in the West. Hesitation and delay are
losing us the golden opportunity. Lay this before the President and
Secretary of War. May I assume the command? Answer quickly."

But McClellan was in no mood to sacrifice the ambition of his intimate
friend and favorite, General Buell, and induced the President to
withhold his consent; and while the generals were debating by telegraph,
Nelson's division of the army of Buell moved up the Cumberland and
occupied Nashville under the orders of Grant. Halleck, however, held
tenaciously to his views and requests, explaining to McClellan that he
himself proposed going to Tennessee:

"That is now the great strategic line of the western campaign, and I am
surprised that General Buell should hesitate to reinforce me. He was too
late at Fort Donelson.... Believe me, General, you make a serious
mistake in having three independent commands in the West. There never
will and never can be any cooeperation at the critical moment; all
military history proves it."

This insistence had greater point because of the news received that
Curtis, energetically following Price into Arkansas, had won a great
Union victory at Pea Ridge, between March 5 and 8, over the united
forces of Price and McCulloch, commanded by Van Dorn. At this juncture,
events at Washington, hereafter to be mentioned, cause
