 Most of the equipment , arms , and machinery at the Little Rock Arsenal was removed to east of the Mississippi River by order of <unk> Gen. Earl Van Dorn in April and May 1862 , and accountability for it is lost at that point . By all appearances , the equipment was sent down the river to Napoleon , Arkansas , and from there to Jackson Mississippi , where it was probably destroyed during the <unk> campaign in the early summer of 1863 .
