Hog Island, Philadelphia was the world's largest shipyard during the Great War and needed to be protected. 800 Krag Jorgensen rifles were issued for its defense. From a hearing before congress published January 30, 1919:
As a further evidence of the fact that Hog Island was a matter of concern to our enemies during the war, we found it necessary to maintain a very comprehensive and high grade guard system, consisting of 1 major, 17 commissioned officers, 89 noncommissioned officers, 411 privates, and 27 civilians, a total force of guards of 545, which force was reduced to 227 immediately upon the signing of the armistice. The guards were all armed with military equipment consisting of 800 rifles (Krag Jorgensen), 100 revolvers, 3 machine guns, 25 blackjacks, 597 batons, 38 handcuffs, and 700 whistles.
