Did Joyce write courtesy of a ___?

“ULYSSES” GRANT

Think of a Civil War general whose first name matches the title of a famous James Joyce novel about a day in Dublin.

This clue plays on the double meaning of "courtesy of." The phrase hints at the novel Ulysses by James Joyce, but the answer twists it by replacing "Joyce" with "Grant"—as in Ulysses S. Grant, the Civil War general and U.S. president. The word "courtesy" suggests the answer is a name (Grant) "given" or attributed to Ulysses, blending literary and historical references in a pun.
