"Remember the Maine" was the cry 100 years ago.

The sinking of the battleship USS Maine in Havana Harbor proved to be the momentum for the U.S. entry into the Spanish-American War in 1898.To commemorate the occasion, the U.S. Postal Service has issued a new 32-cent stamp. Featured on the stamp is a line drawing of the Maine with the slogan on top "Remember the Maine." Below is "United States of America." The stamp denomination "32" flanks the "United States of America." The Postal Service has printed 32 million of these offerings.

Sent to Cuba in 1898 to protect American interests, the USS Maine was rocked by a mysterious explosion while moored in Havana Harbor on Feb. 15. More than 250 American sailors were killed. Many more were injured. An investigation could not determine the cause of the explosion - but the majority of people blamed the Spanish.

The American press used the popular slogan "Remember the Maine" to support entry into the war. Two months after the sinking, America declared war on Spain.

First-day covers of the stamp are available via the Stamp Fulfillment Service of the Postal Service. Each cover is postmarked with the official first date of issue cancellation. You may call 800-STAMP-24 for more details.
