Can two advisors and just one elephant hold off a lone chariot?
These answers restate the rules implemented by our open-source engine, which follows the WXF laws and is regression-tested against the official 110-diagram repetition casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it against the engine before publishing.
Direct answer
Often, yes, though the missing elephant matters more than it might seem. Two advisors already give the general solid coverage of the central palace points, which is most of what holds off a lone chariot. But one elephant fewer means one fewer defended point outside the palace, and a well-placed chariot can sometimes use exactly that gap to make progress it could not otherwise.
Why the advisors do most of the defensive work here
The general's safety against a lone chariot depends heavily on the advisors covering the central palace points a chariot would otherwise use to deliver check from close range. With both advisors present, this coverage is largely intact regardless of how many elephants remain, which is why the position is usually still holdable.
Where the missing elephant actually costs something
Elephants defend key points outside the palace and block certain approach squares a chariot would otherwise use freely. With only one elephant left, the side of the board that elephant does not cover becomes more accessible, and a chariot supported by anything else, even a single soldier, can sometimes exploit that gap where a fully intact defence would not allow it. See advisors and elephants for the general defensive principles this depends on.

Is losing one elephant always dangerous?
Not always, it depends heavily on which side of the board the surviving elephant covers relative to where the chariot is operating.
Does it matter which elephant was lost?
Yes, since the two elephants cover different points; which one remains determines which flank stays properly defended.
