Long-arms of the era were entirely capable of bringing down an elephant. While admittedly several of them could cause disruption sufficient for charging infantry to exploit, the odds of the Union successfully using the gift to any real strategic advantage is pretty low.

...Although an elephant is strong enough to wear some measure of steel... but no, that's veering a bit too far from what could have been historically expected.

South would have just used a punt gun or a cannon to take those elephants out

I don't even think those would have been necessary. IIRC, elephant hunters often just used shotguns for their work, and long arms of the era packed far more punch.
