The Yankee Doodle Mouse.

As Tom and Jerry stage their typical fight sequences, the patriotic soldier theme of the title is evidenced by such things as a carton of eggs labeled "Hen Grenades"; Jerry dropping light bulbs from an airplane like bombs; and Jerry sending a telegram with the message "Sighted Cat - Sank Same." Musical phrasings from various patriotic war songs are heard throughout. The cut scene after Jerry hitting Tom with the board 4 times was cut from the 1950 reissue print for a war bond joke, and the original footage is currently considered "lost" due to the negatives destroyed in the 1978 George Eastman House fire.
