As a result of Malietoa Laupepa's death, Mata'afa Iosefo returned from exile and was elected to power by a council of Samoan chiefs.
After the conflict, Mataafaite forces, as they were sometimes called, retreated to the stronghold of Vailele and thus began several American and British expeditions into the dense jungle to find the chief's men.
On April 1, the expedition of 26 marines, 88 sailors and 136 Samoans left the coast for an attack on the landward side of Vailele, leaving the protection of naval gunfire support.
Close quarters combat and skirmishing continued for a while, the rebel Samoans repeatedly attacked the expedition's front line and several of them were killed or wounded.
A retreat was sounded, and Landsdale ordered his men to save themselves so the expedition began to fall back which left the lieutenant alone under heavy fire.
Refusing to leave his commander, Ensign John R. Monaghan, picked up a rifle and with three others, went after Landsdale and when they were carrying him out of action, Seaman Norman Edsall was shot and killed.
[3] Once again, Landsdale ordered his rescuers to flee but they held their ground waiting for reinforcements and were killed by fast approaching Samoan rebels.
