A bomb in a horse-drawn wagon exploded on Wall Street in front of the J.P. Morgan building in New York City, killing 38 and injuring 400.

The Wall Street bombing was the deadliest bomb attack on American soil for seven years. The horse and wagon were vaporized. An automobile was hurled into the air, and glass was shattered for blocks. The J.P. Morgan company decided not to fix the visible damage to 23 Wall Street, and it is still visible today.
