Revolutionaries didnt have much money and procuring weapons and ammo required connections since none was being smuggled in.
Also these folks were really very very young without any training but they compensated greatly by their will and drive and desire. Their Life spam was hardly more than 5 years before being caught or they had to escape /exile.
All of the soldiers returning from war were rarely allowed to carry back their war trophies. There was only one effort part of Hindu-German Conspiracy wherein Germans ( San Francisco Attache Fran Von Papen later Chancellor of Germany) via Gahdars in US coordinated shipping of consignment of arms to Bagha Jatin et al in Orissa. British had already infiltrated the Ghadar movement and most of these revolutionaries were caught - Kartar Singh Sarabha, Pingle et al.
We do have a member here whose great grand uncle was part of this movement.http://en.wikipedia.org/wiki/Hindu%E2%8 ... Conspiracy
"In the United States, an elaborate plan and arrangement was made to ship arms from the country and from the Far East through Shanghai, Batavia, Bangkok and Burma. Even while Herambalal Gupta was on his mission in China and Japan, other plans were explored to ship arms from the United States and East Asia. The German high command decided early on that assistance to the Indian groups would be pointless unless given on a substantial scale. In October 1914, German Vice Consul E.H von Schack in San Francisco approved the arrangements for funds and armaments. $200,000 worth of small arms and ammunition were acquired by the German military attaché Captain Franz von Papen through Krupp agents, and arranged for its shipment to India through San Diego, Java, and Burma. The arsenal included 8,080 Springfield rifles of Spanish-American War vintage, 2,400 Springfield carbines, 410 Hotchkiss repeating rifles, 4,000,000 cartridges, 500 Colt revolvers with 100,000 cartridges, and 250 Mauser pistols along with ammunition. The schooner Annie Larsen and the sailing ship SS Henry S were hired to ship the arms out of the United States and transfer it to the SS Maverick. The ownership of ships were hidden under a massive smokescreen involving fake companies and oil business in south-east Asia. For the arms shipment itself, a successful cover was set up to lead British agents to believe that the arms were for the warring factions of the Mexican Civil War. This ruse was successful enough that the rival Villa faction offered $15,000 to divert the shipment to a Villa-controlled port.
