We present preliminary results from a high resolution resimulation of a galaxy in the first 500 million years of its life. The protogalaxy sits at the intersection of filaments which provide a steady supply of smooth cold gas as well as a pathway for denser substructures falling onto it. Fed in this way, the protogalaxy grows a dense, thin, rapidly spinning disk which undergoes gravitational instability leading to dense gaseous clumps. Star formation in these clumps transforms them into stellar clusters. One of the byproducts of this intense star formation is a far reaching galactic wind, powered not just by the protogalaxy sitting at its epicenter but by the winds produced by the dense, star forming substructures feeding the protogalaxy. Despite the impressive presence of the galactic wind, the cold gas supply is hardly affected.
