How did antislavery forces hide their guns when they shipped them from the Northeast to Kansas?

Antislavery forces concealed their guns during transport from the Northeast to Kansas by disguising them as ordinary goods, often using crates labeled with misleading descriptions. They sometimes shipped the weapons hidden among agricultural supplies or other benign cargo to avoid detection. Additionally, they utilized a network of sympathetic allies who facilitated the covert movement of these arms to support the antislavery cause in the violent conflicts that arose in Kansas.
