On 8 September 1429 Valois forces including Joan assaulted Paris and failed. Joan was wounded.

Context

A captain who lifts one siege can still join a costly failed storm of another city. Split the rows.

Joan of Arc is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

Why it matters

Humanitarian-cost path. High confidence on the failed assault.

A wound is not a miracle. It is a military-cost date.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
