The fact is, these veterans were about fought out, and became almost inert.

They did not, at the last, even press Hancock, who was still strong in artillery, and he withdrew his main body in good order, losing however, the 27th Connecticut regiment, which was posted at the apex of his line on the south, and was not brought back in time, in consequence of the failure of a subordinate officer to carry out his orders.
Before Hancock left, his line was taken in reverse, and he was obliged to throw back part of his force to the left to resist Anderson, who was trying to force the passage of Mott Run.

The line in that direction was firmly held by Colonel Miles of the 61st New York, who was shot through the body while encouraging his men to defend the position.
Stuart's command had lost 7,500 in his attack, and it could hardly have resisted a fresh force if it had been thrown in.

General William Hays, of the Second Corps, who was taken prisoner, says they were worn out, and Rodes admits in his report that Jackson's veterans clung to their intrenchments, and that Ramseur and others who passed them, urged them to go forward in vain.
Before the close of the action Hooker was importuned for reinforcements, but to no avail.

Perhaps he intended to send them, for about this time he rushed out and made a passionate appeal to Geary's men to charge and retake the works they had lost; promising to aid them by throwing in a heavy force on the enemy's left flank.
