Kiyonao Ichiki, commander of the Japanese unit
Kiyonao Ichiki, commander of the Japanese unit

The Battle of the Tenaru was a land battle between the Imperial Japanese Army and Allied forces on August 21, 1942, at Guadalcanal in the Solomon Islands during World War II. The U.S. Marines were defending the Lunga perimeter around Henderson Field, which had been captured by the Allies on August 7. The Japanese unit, commanded by Kiyonao Ichiki (pictured), was sent to recapture the airfield and drive the Allied forces off the island. Underestimating the strength of the Allied forces, Ichiki's unit conducted a nighttime frontal assault on Marine positions at Alligator Creek on the east side of the perimeter and were defeated with heavy losses. The Marines counterattacked after daybreak, and about 800 of Ichiki's original 917 men were killed. After Tenaru, the Japanese realized that Allied forces on Guadalcanal were much greater in number than originally estimated and sent larger forces for their later attempts to retake Henderson Field.

Obverse and reverse of an 1836 Argentine eight-escudo coin

The Argentine real was the currency of Argentina between 1813 and 1881. From 1822, it was subdivided into ten décimos. The sol was also issued during this period and was equal to the real, while the peso was worth eight reales and the escudo was worth sixteen reales. This 1836 eight-escudo gold coin was issued by the Argentine Confederation, a predecessor state of modern Argentina, featuring a portrait of the Argentine politician and general Juan Manuel de Rosas on the obverse, and a depiction of a mountain with crossed flags and cannons on the reverse. Only six of these coins are known to exist; this one forms part of the National Numismatic Collection at the Smithsonian Institution.
