mcclellan was happy that the union army failed to capture richmond.
mcclellan was confident that his army would capture richmond quickly.
mcclellan felt the union administration had supported the army well.
mcclellan blamed the union administration for the union armys problems.

Explanation:

The passage states that the government (which can be related to the Union Administration) has not sustained (supported) the army. McClellan says "you have done the best to sacrifice this army", indicating he blames the Union Administration for the army's problems. The first option is wrong as he is not happy about the failure. The second option is not supported as there's no indication of quick capture confidence. The third option is contrary to what he says (he says the government has not sustained/supported well).

Answer:

McClellan blamed the Union Administration for the Union army's problems.
